#1045 Add Hebrew, Turkish, Ukrainian, and Greek — 20 languages total Pull request opened by javuto Add Hebrew, Turkish, Ukrainian, and Greek — 20 languages total Problem Coverage ended at 16 languages; Hebrew was the notable missing RTL language, plus the significant remaining LTR gaps (Turkish, Ukrainian, Greek). Change • New languages — full 671-key catalogs each, type-checked against the English contract and enforced by catalog-parity tests: • Hebrew (he-IL, עברית 🇮🇱) — RTL • Turkish (tr-TR, Türkçe 🇹🇷) • Ukrainian (uk-UA, Українська 🇺🇦) — complete Slavic ICU plural categories (one/few/many/other) • Greek (el-GR, Ελληνικά 🇬🇷) • RTL extended: Hebrew added to the

set, so the UI mirrors via

dir="rtl"

when switching to it and resets to

ltr

for every other language. The direction-flip test now covers Arabic → Hebrew → English. • Cross-device sync: backend

Remaining candidates would be regional variants (pt-BR, zh-TW) rather than whole languages. jmpsec/osctrl
