How to save files containing int'l characters in kwrite ?

Hi, I am pretty sure that this was recently discussed on this list (even solved), but I couldn't dig it out of the archive. I really tried, but (sorry) have to ask again. My problem is as following: - I can change keyboard layout and type local latinic characters in kwrite editor. I use TT fonts (e.g. courier new) and everything looks fine, but after I save the file and read it back into editor, all international (local) chars appear as "?". Hope this can be solved, appreciate all suggestions, including switching to another editor, whatever. TIA -- Radule Soskic
