line break after specific no of characters

[php_begins]

Hi.I have need  to insert a line break after  specific sequence of characters..

For example consider the following username,

LONGLONGUSERNAME... I need a line break after 12 characters or till a specific width.

If you're referring to a user name, like the ones here that PHPF's uses SMF, then wouldn't you use CSS?  Set the width and the lines would automatically wrap.

[php_begins]

I tried that and it didnt work.. In CSS the width works only when you encounter a whitespace
