Cyrlitera converts Cyrillic and Georgian URLs and file names to Latin. It works for all post types, pages, and terms. It gives you options to define your own custom characters and enable automatic redirects.
<h3>How It Works</h3>
Transliteration is the process of converting characters from one writing system to another, such as converting Cyrillic symbols to Latin. Because most web software and URLs are designed around Latin characters, using Cyrillic or other non-Latin symbols in links or file names can lead to unreadable URLs, accessibility issues, and even broken links. Transliteration ensures your URLs and file names remain clean, readable, and compatible across all platforms.
Cyrlitera automatically replaces Cyrillic and Georgian characters with Latin equivalents to create clean and readable URLs for posts, categories, taxonomies, products, and custom post types. It also fixes incorrect file names by removing unsafe characters and transliterating them during upload, helping prevent 404 errors and broken media links.
<h3>Examples</h3>
Cyrillic URL before transliteration:
<pre><code>https://example.com/%D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82-%D0%BC%D0%B8%D1%80
</code></pre>
Same URL transliterated to Latin:
<pre><code>https://example.com/privet-mir
</code></pre>
Incorrect file names before transliteration:
<pre><code>%D0%BC%D0%BE%D0%B5_image_290.jpg
A+nice+picture.png
</code></pre>
Readable transliterated file names:
<pre><code>moe_image_290.jpg
a-nice-picture.png
</code></pre>
By using Latin-based file names and URLs, you avoid issues with encoding, broken links, and unreadable paths. This plugin performs the transliteration automatically each time a file is uploaded, ensuring your media library stays clean and consistent.
