    Hi guys,

    [​IMG]

    In my website, I allows user to search for keywords. Here, as you can see, user use very very weird letters. So my question is: how can i limit my users to only use A-Z, a-z and 0-9 ?

    please help guys.

    First, you might check out the Unicode Web site -- to see if the character forms you are presented with are referenced there.

    You will need to use regular expressions to filter this data out. They are a handful, so I would suggest google on this one.
