Hi :)

I need some help. I want to write in Serbian language (latin) and I tried with suggestions here and I still have problem. I have Serbian in my language bar (on my computer) and I set code to Windows-1252 (is this correct?) and when I write letters like đšćč in first moment letters are there, but as soon as I click with mouse somewhere on page, these letters turn to dscc. I hope that someone will help.
Thank you,
Tatjana
