What

Adds Finnish as UI language on the device. The new FI value is wired into the config enum, the string lookup, the language cycle and the settings label, and Finnish is included in the Latin glyph coverage check and the README language list.

  • src/ui/strings/UiStrings.fi.inc — new, 340 strings
  • src/config/AppConfig.h, src/ui/UiStrings.cpp, src/ui/UiLocalization.cpp — language wiring
  • tools/check_ui_font_coverage.py, README.md — include Finnish

No font regeneration is needed: the existing JetBrains Mono subsets already cover Ä and Ö, and the translation avoids Å/å, which the fonts do not contain.

Fitting the fixed-size labels

Finnish words are long, so several strings are written to fit the EEZ layout rather than translated literally. Every sensor info page was checked against screens.c: the body text must stay within six lines of the 760 px label before the threshold list, and threshold lines must not run under the tab buttons or past the right screen edge.

Two places where the Finnish word does not fit have a short comment in the string table explaining the choice:

  • the settings button (70 px) uses VALIKKO; ASETUKSET is clipped
  • the card unit label (40 px) keeps Index; Indeksi wraps. The other Latin-script locales keep Index as well

Out of scope

While reviewing the UI I found strings that no language can translate, because they are hardcoded in screens.c or built in C++: the GRAPH, LOGS and UNITS buttons, the LOG: and LANGUAGE: titles, and the optional gas page in UiOptionalGasProfile.cpp.

This PR is strictly "translation only".

Add Finnish UI localization
523f738 
Add a Finnish string table and wire the FI language into the config enum,
string lookup, language cycle and settings label. The existing JetBrains
Mono font subsets already cover Ä/Ö, so no font regeneration is needed;
the translation avoids Å/å, which the fonts do not contain.

Include Finnish in the Latin glyph coverage check and README language list.

Reword Finnish sensor warmup status
2f2f155 
"LÄMPENEE" read as a temperature change and could look like a fault.
Use "KÄYNNISTYY" for the warmup label on the VOC, NOx, HCHO and CO
cards; it fits the 120 px label on one line. Match the VOC and NOx
help texts to the English "Blue indicator = sensor warming up."
wording with "anturi on käynnistysvaiheessa".

Explain width-limited Finnish label choices
90a11f6 
Add short comments to the Finnish string table: 'Index' is kept for
UnitIndex and 'VALIKKO' for the settings button because 'Indeksi' and
'ASETUKSET' do not fit their fixed-width labels.

Fit Finnish relative humidity info texts on screen
bd79e59 
The main text wrapped to seven lines and ran into the thresholds list,
which only leaves room for six. Tighten and smooth the wording
(ilmankosteus, ihannealue, fewer repeated verbs) so it fits.

Shorten the Excellent line so it no longer extends under the AH and RH
buttons.

4115ccb 
The main text wrapped to seven lines; tighten and smooth it so it fits
in six, using the same ihannealue and viihtyvyys wording as the other
info pages. Use ihanteellinen on the Excellent line.

Spell out the title as ABSOLUUTTINEN KOSTEUS. The AH page has no graph,
and like the German and Dutch titles it wraps to two lines.

Say epäpuhtaus instead of saaste in Finnish info texts
9cb8885 
Finnish saaste suggests industrial pollution, which is misleading for

Name outdoor particles on the Finnish PM pages
8578405 
The PM pages measure particles, so outdoor pollution reads better as

epäpuhtaus because it combines particles and gases.

Name the gases in Finnish status messages
3b42a1d 
Finnish readers know häkä, hiilidioksidi and formaldehydi better than the
CO, CO2 and HCHO abbreviations, so lead with the word and keep the
abbreviation in brackets. The longest line is 47 of the roughly 50
characters that fit beside the settings button, and the messages keep
plain CO2 because the subscript glyph is missing from the 14 px font.

Use häkävaroitin for the CO alarm in Finnish

Häkävaroitin is the established Finnish word for a CO alarm. The line

so drop it here; the other two CO messages still carry it.
