Transliterating filenames in Wordpress library?

Question

Transliteration

The problem is this: The library contains files with Russian names, but they are not transferred during import / export. Is there a way to bulk rename files?

Answer 1

There is such a plugin from Sergey Biryukov http://wordpress.org/plugins/cyr2lat/ , he can convert slugs on the fly. The names of new files will also be converted to transliteration, but the old filenames will remain untouched for the simple reason that they may already be used in posts.
You can peep the algorithm in the plugin and for each media element in the library, in addition to broadcasting the file, you will also have to replace all previously recognized links in the content (meta fields can also be used) so that you don’t get zombie links that lead to a non-existent media file
