 There is another post about this somewhere on the forums [can't find it ATM] but the issue is with how the data is cached. The work around is to set the cache time to zero.

the problem is in the way the modulehost encodes module content. instead of UTF8, ASCII encoding is used. What you can do is to turn of module caching for all modules, but that comes at a performance cost. If you have the ability to compile the source you can make the fix yourself (look for system.encoding.ascii in te source)

see here for related gemini issue: http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=11175&PROJID=2
