[TYPO3-english] Restrict user input in backend

[Tomas Havner]

Hi,

I'm having problems with users who puts other characters than a-z 0-9 in the 
title field of the page. This results in strange url:s when realurl 
transforms the title-field.

Can i restrict input in the title-field of the page, or is there something 
in realurl that I can use?


Regards

Tomas
