Unusual characters in username can mess with formatting

[altenbach]

user Q<UL has a "<" in his name.

When replying to a post and quoting the original post, this character is messing up the html and the first line of the quoted text shows up as a single character "Q" on a single line instead of the words "Q>UL wrote".

Hi altenbach,

I see what you mean - I will add this to my list of bugs.

Thanks!
