Remove illegal characters from string?

Hi,

Does anybody know how to remove illegal characters from a string?
The find function in Lua only seems to find a exact string.

I have a list of illegal chars, for example:

invalidList = ",<.>?;:'@#~]}[{=+)(*&amp;^%$£!`¬| -_"<br><br>text = "Any text as long as theres no illegal character, like ?"<br><br>

I looked into the documentation string.find, string.gsub but can’t find a solution.

Have you tried running string.gsub on text for each character in the invalidList?

cheers,
