i18n: drop the it_CH (Swiss Italian) catalog - #552
Merged
Conversation
it_CH was not a Swiss-Italian localization but a stale, degraded copy of it: 1531 of 1845 strings (83%) were byte-identical to it, and the divergences were older translator-choice variants (cartella/directory, collegamento/link, fallito/non riuscito) rather than Helvetisms, plus ~68 unreviewed fuzzy matches and ~140 strings left untranslated that it already covers. gettext only falls back it_CH -> it -> C when it_CH.mo is absent, so shipping this catalog gave Swiss-Italian users a worse result than plain Italian (English strings where it is complete). Removing it lets those users fall through to the full, current it catalog. Also drops the now-dead it_CH wiring: the LINGUAS entry, the po/ CMakeLists.txt language label, the redundant [it_CH] .desktop keys (identical to [it]), and the it_CH -> ITALIAN mapping in the Windows NSIS generator. it_CH was app-catalog only (no man pages).

The it_CH catalog file was removed in #552, but the surrounding references were left behind: the LINGUAS entry, the po/CMakeLists.txt language label, the redundant [it_CH] .desktop keys (identical to [it]), and the it_CH -> ITALIAN mapping in the Windows NSIS generator. None affect the build (it is glob-driven and it_CH.po is already gone), but they point at a catalog that no longer exists. Remove them so the tree is consistent.

The it_CH catalog was dropped in #552, but the language picker is not driven by the shipped catalogs: it iterates the hardcoded aMuleLanguages[] table in Preferences.cpp, which still listed wxLANGUAGE_ITALIAN_SWISS. Removing the catalog could not hide it, because UpdateChoice()'s probe marks an entry available when wxLocale reports PACKAGE loaded, and wxLocale falls back it_CH -> it -- so it.mo kept satisfying the check and the entry stayed visible. Remove the table entry (the picker-side twin of the catalog drop) and drop the now-unused 'Italian (Swiss)' string from the po catalogs. Catalogs edited surgically to keep the diff to the removed entry; the stale source-line references CI already tolerates are left untouched.
