I don't know about Java, but the C# standard library is exceptionally well design with respect to variable byte encoding. https://learn.microsoft.com/en-us/dotnet/standard/base-types/character-encoding-introduction https://learn.microsoft.com/en-us/dotnet/standard/base-types... The built-in string.length method is useless (it returns the number of char objects) and I agree that's a problem, but the solution is also built into the language, unlike in JS.

JS these days also has ways to iterate over codepoints and grapheme clusters. If you treat the string as an iterator, then its elements will be single-codepoint strings, on which you can call .codePointAt(0) to get the values. (The major JS engines can allegedly elide the allocations for this.) The codepoint count can be obtained most simply with [...string].length, or more efficiently by looping over the iterator manually. The Intl.Segmenter API [0] can similarly yield iterable objects with all the grapheme clusters of a string. Also, the TextEncoder [1] and TextDecoder [2] APIs can be used to convert strings to and from UTF-8 byte arrays.
