The reason why it is requesting the font to have 1599 is because it was the previous Win value and the original font didn't have the Use of Type Metrics enabled. When updating such cases we expect the upgrade font to inherit the previous Win metrics values.

[vv-monsalve]

The new version is showing tofu in Hebrew (which is the main script for this font)

[emmamarichal]

@vv-monsalve Ah yes, sorry I forgot to link this: meirsadan/david-libre#22 (comment)

[RosaWagner]

Indeed, to summurize the doc, for the VM we would expect:

• use typo metrics to be enabled
• Win metrics values to be transferred to the typo metrics
• change hhea metrics to match the new typo metrics (which are the old Win metrics), because Mac user are less numerous than Windows users
• update win metrics to y-min and y-max

[emmamarichal]

@RosaWagner Yep, I know this, but when I did it, I had a visual difference. I'll check again tomorrow

[vv-monsalve]

@vv-monsalve Ah yes, sorry I forgot to link this: meirsadan/david-libre#22 (comment)

In that case, it will cause a regression, so we should check how permissive or flexible we can be in these cases.
Sadly, it seems we don't have a Hebrew glyphset defined.
@RosaWagner wdyt?

[RosaWagner]

VM: The difference will be expected in Mac, but diff images from Windows should show the same VM as before. Did you mean that you had a difference in Windows?

Glyphset: several possibilities

1. We check first https://github.com/googlefonts/lang/blob/main/Lib/gflanguages/data/languages/yi_Hebr.textproto to see if it contain these codepoints, if not, we can merge and move on.
2. Re-instate these codepoints as zero-width to avoid the tofu as the previous version.
3. We could also specify languages in metadata.pb (like in Noto families), to include all Hebrew languages but excluding Yiddish to force the specimen page to show only the supported languages.

The eng team tend to recommend to not add language tags in metadata for non-noto families (I don't know why, maybe because of subsetting reasons). So asking in the chat before taking the decision would be good.

[vv-monsalve]

VM: The difference will be expected in Mac, but diff images from Windows should show the same VM as before. Did you mean that you had a difference in Windows?

Currently yes (above image), because the font is keeping the original TypoMetrics. It will get resolved once the new font is changed to follow the spec.

On Glyphsets.

Confirming: I'm getting that option 2 would apply if the answer to 1. is "yes". Is it?

[RosaWagner]

@vv-monsalve yes, option 2 would apply if 1 is yes, and if we don’t choose option 3. I don’t know what’s best between 2 and 3. I might be good to talk about it at the meeting tomorrow, but since the font was like 2 before, we may as well just continue this way (simplest solution but not the most accurate for users). It could added in the description that Yiddish is not supported.

[vv-monsalve]

but since the font was like 2 before, we may as well just continue this way (simplest solution but not the most accurate for users). It could added in the description that Yiddish is not supported.

Agree. @emmamarichal After a quick inspection it seems that these marks are not included in our Hebrew subset (please double check it). So the above would be the best solution in this case.

[markhdavid]

1. https://github.com/googlefonts/lang/blob/main/Lib/gflanguages/data/languages/yi_Hebr.textproto

Sorry, but I'm new here. I don't understand. What is the problem? It sounds like you're considering dropping support for Yiddish. I don't understand why that would be. The original corrections to this font that prompted this attempt to push out a new version for Google Fonts was specifically to support Yiddish. Can anyone explain what is going on? I have Yiddish language and Hebrew script expertise.

[emmamarichal]

@vv-monsalve @markhdavid, I just checked the Hebrew subset, here are the glyphs not included and not supported:

ayinaltone-hb
alefWide-hb
daletWide-hb
heWide-hb
kafWide-hb
lamedWide-hb
memFinalWide-hb
reshWide-hb
tavWide-hb
yodhiriq-hb
yodyodpatah-hb
perafe-hb
kafrafe-hb
betrafe-hb
aleflamed-hb

[emmamarichal]

We'll discuss about it in our today meeting.

Note for me: fix an ogonek placement issue

[RosaWagner]

@markhdavid We detected multiple issues in multiple places affecting the API but I believe we need to reassure you on the nature of these issues: the way the Google Fonts API functions makes it almost impossible to drop language support, we can only add language coverage or keep the same as before.

Now everyone bare with me, it is a bit hard to explain.

About the cantillation marks:

What I understand from this issue meirsadan/david-libre#22 (comment), is that Yiddish has never been fully supported by this family because of the lack of cantillation marks. I also don't see this issue petitioning for the addition of these glyphs to be resolved: meirsadan/david-libre#14. The cantillation marks seem to have been replaced by zero-width glyphs in the past to avoid the apparition of squares in sample texts. I believe that this is misleading users and that we should be more explicit about the lack of support for these marks. Another consideration is that we try to avoid tofu appearing in specimen pages.

1. If you are saying that the cantillation marks are not necessary for the support of Yiddish, I suggest to make sure that these codepoints are not used in the sample text used to represent the language: https://github.com/googlefonts/lang/blob/main/Lib/gflanguages/data/languages/yi_Hebr.textproto.
2. If they are not used by the sample text: then they should be removed from the font instead of having them zero-width and misleading users about the glyphset support of the font.
3. If they are used in the sample text then we need to either: keep the zero-width glyphs and be explicit in the description about this lack of support, or exclude this specific sample text for the specimen page (tricky without excluding Latin from the called sample texts)
4. If they are used in the sample text but not necessary for the support of the language: we could eventually consider modifying the sample text so these codepoints don't appear.
5. If now you mean that the cantillation marks were in fact included before: we would need the commit where the sources were still having them so we can include them back in the last sources.

So the first step that you could help us with @markhdavid is to confirm if these cantillation marks are displayed in one of the sentences in the sample_text{…} part of the file used to define Yiddish. You are the only expert in this thread, and even if we try our best, we might miss something. Thanks a lot for your intervention.

About the API subset definition

Apparently some Hebrew codepoints are missing from the subset definition, which is a separate issue. All non-included codepoints will be subsetted by API, meaning they would be missing from the font served by the API (not the version you can download and self-host). We need to make sure the subset is complete so the font is not savagely subsetted.

1. If the sample texts for Hebrew include some of these missing codepoints we need to rectify the subset asap, before merging this PR.
2. If the sample text for Hebrew don't include any of the missing codepoints, we can rectify that a bit later and it doesn't prevent this PR from being merged.

[markhdavid]

Hi @RosaWagner - I can confirm that cantillation marks are not used in the sample text used to represent the Yiddish language (https://github.com/googlefonts/lang/blob/main/Lib/gflanguages/data/languages/yi_Hebr.textproto). I can also assure you that cantillation marks are not necessary for the support of Yiddish.

[markhdavid]

@vv-monsalve @markhdavid, I just checked the Hebrew subset, here are the glyphs not included and not supported:

ayinaltone-hb alefWide-hb daletWide-hb heWide-hb kafWide-hb lamedWide-hb memFinalWide-hb reshWide-hb tavWide-hb yodhiriq-hb yodyodpatah-hb perafe-hb kafrafe-hb betrafe-hb aleflamed-hb

Hi @emmamarichal.

This list contains a few characters that are precomposed variants of character combinations used for Yiddish. The full list of combinations used for Yiddish in its standard orthography, popularly known as "YIVO orthography", is shown here: http://uyip.org/combinations/ The characters in this list corresponding to the combinations used for Yiddish are the following four:

yodhiriq-hb yodyodpatah-hb perafe-hb betrafe-hb

All characters in this list are in the block of Unicode called alphabetic presentation forms. That block contains, among others, characters that are precomposed versions of all the base/mark combinations required for Yiddish, but those versions are not strictly necessary to support Yiddish, since all the same combinations can be composed from base and mark characters found in Unicode's Hebrew block.

Note that none of these alphabetic-presentation-form characters are included in the lang repo's Yiddish language test.

All of that said, some users and software processes do make use of precomposed characters for Yiddish for a variety of reasons, and therefore users may innocently find them included in the text of their documents that seem to contain ordinary Yiddish text, and if they happen to use a font that is missing these characters, they are typically disappointed to find that the glyph gets substituted (with that of another font, or "tofu"). Therefore, it would be nice for this and all fonts to support them. Perhaps it should be considered for the lang repository to add the subset of precomposed characters that correspond to composed combinations used for Yiddish to its requirements, but it's not the way it is done now, and I am not going to vociferously argue for that here in the middle of this PR and stop the show.

[emmamarichal]

Hi @markhdavid, thank you for your explanations!
So, if I well understand, the best solution here would be to remove the cantillation marks from the font.
I see you're waiting for an answer from @meirsadan meirsadan/david-libre#22 (comment), I'll check with him if he can do the modifications :)

Can anyone give a high-level status report? I.e., is this font David Libre now on its way to being served via Google Fonts here: https://fonts.google.com/specimen/David+Libre ? If not, can anyone identify the holdup? Thank you.

[m4rc1e]

Update will be live in a couple of weeks or so.

Update will be live in a couple of weeks or so.

Hi @m4rc1e, it's been close to 3 weeks since the last update, and I'm checking in to see if we're still on track for the change to go live. Could you provide an update on the current status or let me know if there have been any unforeseen delays? Your efforts are greatly appreciated, and I'm looking forward to the completion of this update.

[m4rc1e]

Apologies for the delay. It's graduated from our sandbox server so we only need to push it to the production server. I'm guessing this week or next. Unfortunately, I don't do these pushes myself. I'll ping you once it is live.

I see it's live as of today. It looks good. Here's a screenshot of a prominent user (yiddishsongs.org), highlighting the corrected character sequence double-yod+patah on one particular page (https://yiddishsongs.org/ikh-hob-dikh-lib-vi-a-peysakhdikn-rosl/):

Thank you @m4rc1e, as well as @emmamarichal @RosaWagner @meirsadan @fontef, very much. This could be considered resolved now, at least as far as I'm concerned FWIW.
