I don't understand cyrillic and I only use this plugin to support cyrillic characters of our bulgarian guest editors. It works well, but I found that if a the plugin converts a slug into latin characters and this string allready exists in another slug, the cyrillic letters don't geht converted at all. We use the WPML plugin and there this can happen from time to time.
Furthermore the word "Румъния" gehts converted into "rum'niya" - do you think the apostroph character is a good idea in a URL?
Would be great if you could have a look at it!
Thanks in advance!
