Japanese Characters unreadable from .txt after AJAX loading

For my project i need Japanese Characters ( for those that dont know Kanji and Hiragana) plus their english equivalent loaded into an array.

I did that before with rexrainbows csv2array plugin but i only raw pasted the data into the dataentry field there, not the most elegant version.

so i tryed the same thing with ajax but at that point the Characters get messed up and unreadable.

then i tried to write the data into the array manually with loops.

still the characters are unreadable.

So my question is now: is there a way to use ajax with japanese characters staying readable?

Thanks in advance for your help, it is greatly apreciated! :3

Make sure the server sends it with a UTF-8 encoding.

Thank you a bunch. Worked like a charm :3

actually i have to correct that <.<

only most characters are shown now, there are still problems with a some of them. cant see any conection between them too. some are shown some are not. do i have to change some settings still?
