Yep. I think about this stuff a lot and I still mess this up all the time. I’ve come to realise that string.length in javascript is a footgun. Basically every time I use it, my code is wrong when I test with non-ascii characters. I’ve spent the last decade writing javascript and I’ve never once actually cared to know what half the UTF16 byte length of a string is. The only legitimate uses are internal in javascript (since other parts of JS make that quantity meaningful). Like using it in slice() or iterating - though for the latter we now have Unicode string iteration anyway.
