I have a system running Linux (defaults to utf-
running Joomla 1.0.15 (using iso-8859-1).
Everything worked fine with CommunityBuilder 1.2, but as a preparation for upgrading to Joomla 1.5.x, I upgraded to CommunityBuilder 1.3.1 (and later to 1.4, same problem)
What is happening is that when changing text in the cb_aboutme (a Editor Text Area), the system end up saving utf-8-encoded text into the iso-8859-1 field (and 'ø' is stored as 'ø').
Joomla 1.0.15 uses an old version of TinyMCE WYSIWYG editor, but I think the problem is that CommunityBuilder uses wrong encoding when getting text from the editor. If I modify the profile settings to use No WYSIWYG Editor, text is stored as correct iso-8859-1, but most of my users are not able to handle HTML themselves.
I have a separate test-environment where I can debug. If anyone can point me to the point where CommunityBuilder get text from the WYSIWYG editor, or even better, knows how to fix this issue, I would be very happy..
