This plugin assumes you have a site in two or more languages, and that you are using a separate WordPress install for each language. It helps you create links between the same pages in different 
language versions.
You should have a pattern of parallel sites with urls like http://stephanie-booth.com/en/, http://stephanie-booth.com/de/, http://stephanie-booth.com/fr/. Maybe the page 
http://stephanie-booth.com/en/about is equivalent to the page http://stephanie-booth.com/fr/a-propos. The plugin adds a DBX box in the edit/create page admin form, named “Other Language Slugs”. In 
this case, you’d edit the “about” page, and paste the fr slug (“a-propos”) in the appropriate field.
The plugin will then display a small link to the page in the other language at the bottom of your page, or in your menu bar if you’re using a Sandbox-based theme.
Careful! This only works for Pages, not posts!
For intelligent user redirection when they land on the home page, you might want to try using the technique described here: http://climbtothestars.org/archives/2007/12/28/browser-language-detection-and-redirection/
<h3>Future Development</h3>
Here’s what I’d like this plugin to do, someday:
<ul>
<li>automatically capture URLs like http://stephanie-booth.com/en/a-propos and redirect them to http://stephanie-booth.com/en/about (that’s what happens when people edit URLs directly, just replacing 
the language code — I do it all the time)</li>
</ul>

Helps you create links between equivalent (but different language) pages between WordPress installations.

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 (<code>sanitize_title</code> and <code>sanitize_file_name</code>) 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.
<h3>Advanced Transliteration</h3>
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.
<h3>Adoption Notice</h3>
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.
