FAQ
Why are there different length values?
JavaScript string.length counts UTF-16 code units. Graphemes count visible characters. Code points count Unicode scalar values. Bytes count UTF-8 encoded size.
Which count should I use?
For user-visible text, use graphemes. For storage, use bytes. For programming, code points are often most useful.
