Good, but you shouldn't rely on stripping a list of invalid characters.
It's safer to strip any character that doesn't belong to a whitelist. This code
"ínó".replace(/[^a-z0-9]/ig, "");
will delete from the string any characters that are not in the ranges
a-z or 0-9.
Your aproach would allow the user to insert (c)∫∂æ†∑Ω crappy characters :(
Anyway, don't forget to replicate the validation on the server side.
