Thanks nant for the reply.
It's all iso. Well, except the sql collate and language that is set to utf by default.

I've tried several times reinstalling the whole joomla... and community builder only allows me to install spanish in UTF. But then I see strange characters as "Idioma Español para Community Builder (completo)."

Any idea? Perhaps the CB installer is UTF encoded by default?

CB installer has nothing to do with language.
look in language files - both Joomla and CB for problematic language strings.

CB itself supports UTF-8.

For Joomla, you need to:

1) have a language file where the define of _ISO is utf-8.
2) edit database.php (search for utf8 and uncomment that line).

You then need to check the page source to be sure that the header contains utf-8 and not ISO setting.

Then you need to use CB language file with ISO.

However, always save your language files without BOM. Indeed a BOM as well as any space or blank line before "<?php" or after "?>" in any php file, including language ones, will break your headers outputs and might introduce bugs in your web-site, including for your language charsetss settings.

We are working to simplify these charset headaches, but it's not yet there.
