Is there a way to detect whether there are symbols/anything other than actual letters in a textbox?

string.gsub("somet23^7hing","%A","") -- returns only the letters string.find("somet23^7hing","%A") -- not nil if there are any non-letters

How exactly would you use gsub into a if statement?

local isSymbol = str:match("[%s%w%p]") == nil but I might make a function with string.byte
