Optional wordbreaks in textboxes

Sometimes you have a long word in a text-box that does not quite fit on its line and therefore jumps into the next line, leaving a not so nice gap in the line before. Does WIX have any special character to indicate an optional wordbreak, something like “mathe~matics” that can be used to automatically dampen the problem? Or are there any other techniques?

Thank you for any help.
