Allow non-Latin characters (Cyrillic, Chinese, Arabic, etc.) in module and page URLs instead of auto-replacing them with underscores. URLs are always stored in decoded, human-readable form (e.g. https://www.example.com/zh/示例-測試頁面 or https://www.example.com/ar/مثال-صفحة), while incoming requests accept both encoded and decoded formats and resolve to the same resource - eliminating canonical URL duplication. The same rules apply to FTP file name uploads.
