At first I apologize for my english.
I have install "Login With Ajax". On form submitting instead of text, like "Введите имя" (Russian), it returns gibberish.
The site encoding is UTF-8 and any other file on site is in UTF-8 to.
The problem would have been easier if I had to display only Russian characters. The fact that I am creating a template and I'm going to sell it en masse. So If the admin, for example, any Arab will set in the WP settings by default Arabic lang., then the output Ajax messages will be displayed not correct.
I have also tried to display plugin form on default WP template (twentyten), and there also displays wrong russian encoding on form sending.
Thanks in advance
