I would be surprised if most languages implement it that way. Counting code points would be a start and would solve this particular problem. But that’s not glyph count. You really need to count grapheme clusters. For example two strings that are visually identical and contain “é” might have a different number of code points since one might use the combining acute accent codepoint while the other one might use the precomposed “e with accute accent”. Even a modern language like Rust doesn’t have standard library support for counting grapheme clusters; you have to use a third party one. And if you do count grapheme clusters then people will eventually complain about that as well (“TIL that getting the length of a String in X takes linear time”).
