Character loss due to encoding

If a character such as Hangeul goes through this library, some of the characters will be lost.
Perhaps an error is caused by letters exceeding 2 byte.

I think this is an error caused by this module using string-width module.
Pure Javascript can calculate the exact number of characters in Unicode characters.
(가.length is always 1)

However, the string-width module appears to calculate the number of bytes, not letters.

Happy to replace string-width if there is a better alternative.

I don't know why this project trying to use string-width module, is there an example that can't handle with pure JavaScript .length method?
