why are national letters (ěščř) converted to html special chars?

[MayheM]

Sorry I must bother you again, but adding mentioned option to gsconfig.php didn't helped.

Code:

# WYSIWYG Editor Options

define('GSEDITOROPTIONS', 'entities : false');

I corrected it in xml files manually, but when I edit for example title in GS backend again, it converts string to special chars again. I think it has nothing to do with WYSIWYG, becouse it converts site name too (form field without WYSIWYG)
Any other ideas?

EDIT: The problem is in htmlentities() function used in function safe_slash_html() and in settings.php for $SITENAME, so I removed it. Now it works as I expect What do you think? Can I let it as I've got now without any secure vulnerabilities?
