There are various Unicode characters which are valid and have valid uses, but can also be used to do slightly odd things like this. In this case, the user hasn't used normal spaces. In this case, he used: https://www.compart.com/en/unicode/U+1160

We generally recommend manual moderation if it becomes a problem, though you can also block specific characters with censoring.
