Does the name contain accented characters?

MySQL would treat accented characters the same e.g. é and ë

Failing that, maybe there's an add on at play in which case you should try again with all add ons disabled.

Now i found in MySql fields with username Ланочка in tables xf_post and xengallery_media. Deleted them also but still same
