self registration and html entities

[piXelshooter]

I use SelfRegistration on a german installation, therefore there need some charakters like ä displayed as messages. But instead of ä, I see ä in my site: the referenced text is referenced again! It is saved correctly in the lang files. Other strings are not encoded again, they get decoded: So, I get a 'ä' in the source text, which looks quite strange...
