special characters

i want to cope and past only numbs and the chr "." for the ip string but idk a key word to target all special char i only fond string letters and digits that cover specific chr

EDIT: I have now found the solution. I went to my font and added a new range, and added ASCII values. I have now solved the problem. I have not had any success in being able to draw text with special symbols. I have had luck using the chr() function for standard letters, but I am having issues...
