Cyr to Lat Enhanced

Description

Cyr to Lat Enhanced automatically converts Cyrillic, European and Georgian characters in post slugs, term slugs and media file names into Latin characters.
It helps maintain clean, readable and consistent URLs on WordPress sites that use non-Latin scripts.

The plugin integrates directly with WordPress core sanitization (sanitize_title and sanitize_file_name) and performs transliteration at the moment slugs and filenames are generated.
It does not modify post content, titles or front-end text. Its scope is strictly limited to URLs and file names.

On activation, existing post and term slugs are converted in the background using safe, batch-based processing via WP-Cron.
WordPress core APIs are used to preserve permalink integrity and existing redirects.

Transliteration is based on an ISO 9-style mapping table with built-in support for:
– Russian
– Belarusian
– Ukrainian
– Bulgarian
– Macedonian
– Georgian

Locale-specific adjustments are applied automatically, and the transliteration table can be customized using a public filter.

Cyr to Lat Enhanced is intentionally lightweight and focused:
– no admin interface
– no settings pages
– no bidirectional conversion
– no data collection or tracking

The plugin continues the cyr2lat / cyr3lat lineage and remains compatible with the original approach introduced by Sergey Biryukov.

Advanced Transliteration

For advanced transliteration needs such as full content conversion, bidirectional processing, extended language rules and fine-grained control, consider the separate plugin:
https://wordpress.org/plugins/serbian-transliteration/

That plugin is designed for complex multilingual setups and broader language processing beyond slugs and file names.

Adoption Notice

This plugin represents the continued maintenance of the original “Cyr to Lat Enhanced” project from the cyr3lat lineage.

The project has been revived to ensure long-term stability, modern WordPress compatibility and responsible maintenance, while preserving the original behavior and purpose.
