I think you rarely need it. May I know what is your usecase that you need this often?

- rswail 3mo agoExtract the nth grapheme from a string of Unicode codepoints. Codepoints are 32-bit values. Take into account that some Unicode codepoints work together to combine to form a grapheme which then links to a glyph for display. If you use UTF-8 internally, you will be expanding out to full 32 bits when scanning the vector anyway. So if memory isn't an issue (and most of the time it's not), indexing a vector by codepoint (ie 32 bits) makes more sense from a processing POV.
