Remove special and unwanted characters

[eluser]Yash[/eluser]
Hi,

I'm trying to enter a input value into url segment. Now problem is user can input any character so I want to remove all not allowed characters like ' " {[} etc...

I think I'm missing something.

Any thought?

Thank you

What if you ran form validation instead, to restrict what they entered? That way no special characters got entered in the first place.
