Cyr to Lat Enhanced converts Cyrillic, European and Georgian characters in post slugs, term slugs and media file names into Latin characters. It helps ensure clean, readable and consistent URLs on WordPress sites that use non-Latin scripts.
The plugin integrates directly with WordPress sanitization and performs transliteration at the moment slugs and filenames are generated. It does not modify post content, titles or any front-end text. Its scope is strictly limited to slugs and media file names.
On activation, existing post and term slugs are converted in the background using safe, batch-based processing. WordPress core APIs are used to preserve permalink integrity and existing redirects.
Transliteration is based on an ISO 9-style mapping table with support for Russian, Belarusian, Ukrainian, Bulgarian, Macedonian and Georgian characters. Locale-specific adjustments are applied automatically, and the transliteration table can be customized via a public filter.
Cyr to Lat Enhanced is intentionally lightweight and focused. It provides no admin interface, no settings pages and no bidirectional conversion. The plugin does not collect data, track users or perform any actions outside its defined purpose.
The plugin continues the cyr2lat / cyr3lat lineage, including compatibility with the original cyr2lat plugin by Sergey Biryukov.
Advanced Transliteration
For more advanced transliteration needs, including extended language support, bidirectional conversion, content-level processing and additional controls, consider the Transliterator plugin.
Transliterator is designed for complex multilingual setups and offers significantly broader functionality beyond slug and filename transliteration.
