You can use this function to return a specific character at a specific position within a string, with the index starting at 1 for the first character. If no character is found or the string is shorter than the value given to index, an empty string "" is returned.
|str||The string to check.|
|index||The position to get the character from.|
str1 = "Hello World";
str2 = string_char_at(str1, 7);
This will set str2 to the seventh character ("H" counting as the 1st) in string str1, in this case "W".
