Created Unassigned: HtmlEditor: Occasionally Unicode Replacement Character [27656]

Hi,

i am using the Html Editor in an Update Panel, not Html Editor Extender, because i needed the button "insert Plain text";
and now i encountered a problem finding unicode replacement characters (�) in my database instead of german umlaute(ä,ö,ü); but this happens just occasionally; i still cannot reproduce it; it just happens every about 100 records;

i assume it´s the same like in issue [26753](http://ajaxcontroltoolkit.codeplex.com/workitem/26753), but i am using linkbuttons; i just use some 1px imagebuttons for the modulpopupextender;

i just want to know if anybody else has encountered the same behaviour;

AjaxControlToolkit.dll: Version 4.1.7.123

Regards,
Alex
