Warning
This is only for demo purposes, not a published package.
This is a demo replacement for string-width using unicode-segmenter/grapheme.
This actually performs better than other libraries, especially on the non-alphabet characters.
string-width is basically for the TTY environment, not general purposes.
It is implemented in a "best-effort" manner to support the widest possible range of terminal environments or typography system. It is very heuristic and there is no well-defined resolution.
If you rely on string-width for some other purposes, I strongly recommend reevaluating its behavior.
- If it is about a storage or transport system, you should measure it based on the byte size.
- If it is about a display system, you should measure it based on the visual segments (aka graphemes).
Consider using a Unicode-aware alternative such as Intl.Segmenter or unicode-segmenter/grapheme.
