render - encoding problems [solved]

I have referred to cookbook on solving special symbols localization problems, and after changing any of main files eg. index.php (main) GD captcha stops working, and IE stops recognizing .css files, I believe this could be overall render problem. What solution could be in this case(use of special characters in each page)?

Detailed problem stated here:

Thanks in advance!



Did you check the encoding of the files?

Yep, files were encoded to UTF-8 with BOM, that [BOM] was main problem. If such a problem occurs you should use UTF-8 NO BOM (with editor like UltraEdit or similar).
