Hi,
I would like to force users to follow IO 8859-1 (Latin-1) (abcd123*-.. etc. i.e. not Chinese characters). Is this possible? I need to know the best, less "heavy" way to do this since the performance is already on the limit in this form due to constantly expanding requirements... But really, any hints of how I could achieve this would be great. My guess is that it will require some callback with regular expression validation or similar, but I hope there is some easier way.
Thanks in advance/Jesper
