[HELP] Check if string has special characters

[..:D&G:..]

Hi, so it's been a while since I've used this... How can I check if a string has special characters like /\';"£$!@~ etc and also numbers? I need the string to only be a string of letters.

I tried this but the name can still have / in it when the string is "MyString/"

local function checkValidCharacterName(theText)
	if(string.find ( theText, "[^a-zA-Z]")) then
		return false
	else
		return true
	end		
end

Thanks.

What about

string.find(theText, "%A")

Nope, I can still add a / at the end of the string and it works

Your code has to be somewhere wrong.

val = string.find("MyName", "%A")
outputChatBox(tostring(val)) -- nil
val = string.find("MyName/", "%A")
outputChatBox(tostring(val)) -- 7

Didn't know it has to return a number or nil, thanks
