accented letters on case update

When update cases with a text with accented letters (à è ò ì…) and back to list cases, after the case crash and show a blank page
(suitecrm latest version)
I think maybe a tinymce bug.

Works ok for me in SuiteCRM 7.2.1. Do you get any error if you turn on errors/debugging?



the problem was in ajax: Removed ajax ui from cases, all cases works fine, but accented letters always show as � (but only in case updates)
