URL-Encode links with special chars

[jadyndev]

The links to the NORTx overview page on the camp23 site is broken in Firefox (116.0.3 apple-darwin):

The source shows: /c/camp2023/Nerds der OberRheinischen Tiefebene und der xHain (N\:O:R:T:x)
This is converted to: /c/camp2023/Nerds der OberRheinischen Tiefebene und der xHain (N/:O:R:T:x), which is invalid

This can be fixed by urlencoding the link in the source like this: /c/camp2023/Nerds%20der%20OberRheinischen%20Tiefebene%20und%20der%20xHain%20(N%5C%3AO%3AR%3AT%3Ax)

(encoding the \should be enough)

Just for the sake of completeness, where is a working link: https://media.ccc.de/c/camp2023/Nerds%20der%20OberRheinischen%20Tiefebene%20und%20der%20xHain%20(N%5C:O:R:T:x)
(We should have stripped down that tag to NORTx, and skip the long form – but now it's proably to late to change this…)

The corresponding line where we proably should fix this is here:

voctoweb/app/views/frontend/shared/_event_metadata.haml

Line 18 in c4e7039

!= link_for(event.conference, tag)

Since this is more than a year later, and links have been broken since then anyway, I just renamed the tag to NORTx. Nothing is lost, as any links to it were broken anyway. Even if you could theoretically link to it by manually fixing the link, I think breaking those links is a sacrifice we can make.

but now it's proably to late to change this

It's been broken for so long that now it's already late enough to change this again.

The tags should have been sanitized beforehand anyway. I don't think the code there needs to be updated unless another "saner" tag - for lack of better ways to express it - comes along and runs into this issue.
