From 0b928b6810a046c598c89d1bd04e314fbe2dcbd5 Mon Sep 17 00:00:00 2001 From: German Khokhlov Date: Wed, 28 Oct 2026 12:55:20 +0400 Subject: [PATCH] i18n(ar): register Arabic as the first right-to-left language MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add ar to LOCALES (picker name العربية) and RTL_LOCALES, so turns rtl; any ar-* tag maps to it. - Intl formatters get ar-u-nu-latn: numbers and dates keep Western digits like the catalog, whatever the browser's ICU picks for Arabic regions. - HUD quantities keep a space before an Arabic unit (2069.0 كم), as in Chinese, instead of running digits into the word. - Codes and product names that stay Latin go to same-as-english.json.
