I mean this isn't quite a question more of a complaint but I'll assume you want a work around:
a lot more work than just using string_digits, but hey, beggars can't be choosers.
oh this also doesn't work if your string has periods in it that aren't meant to be part of the decimal. So if that's a problem you just need to add in a bit to check if the character's before and/or after the period are numbers.
It's not that hard (especially compared to other stuff that games require) if you need to do it a lot just package it into a script and you're done. Sure you can't 'easily' do it but nobody said programming was easy.
Code:
var newS = "";
for(var i=1; i<=string_length(string); i++) {
var c = string_char_at(string, i);
newS += string_digits(c);
if(c == '.') newS += '.';
}
number = real(newS);oh this also doesn't work if your string has periods in it that aren't meant to be part of the decimal. So if that's a problem you just need to add in a bit to check if the character's before and/or after the period are numbers.

I wrote a post on this subject https://yal.cc/gamemaker-checking-whether-a-string-is-a-valid-number/
Code:
/// string_is_real(string)
var s = argument0;
var n = string_length(string_digits(s));
return n > 0 && n == string_length(s) - (string_ord_at(s, 1) == ord("-")) - (string_pos(".", s) != 0);
