fix(i18n): fix character encoding in locale files

Fixes mojibake (garbled text) in 28 locale files caused by incorrect UTF-8 encoding. Replaces double-encoded characters with proper Unicode representations.

Examples:
- German: "Öffentliche" → "Öffentliche"
- Spanish: "reproducción" → "reproducción"
- French: "dépôts" → "dépôts"
- Czech: "ZaÄíná" → "Začíná"
- Finnish: "että" → "että"

Affects cs-CZ, de-DE, el-GR, es-ES, fa-IR, fi-FI, fr-FR, ga-IE, hi-IN, hu-HU, id-ID, is-IS, it-IT, ja-JP, ko-KR, lv-LV, nl-NL, pl-PL, pt-BR, pt-PT, ro-RO, ru-RU, si-LK, sk-SK, sv-SE, tr-TR, uk-UA, zh-CN.

No functional changes - purely encoding correction for proper display of non-ASCII characters.
