javascript - how to convert unicode string to ascii

ascii, javascript, unicode

Solution

There is only a short list of characters that can be safely carried through in a path component of a URL.

unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

All the other characters will have to be either removed (if you're creating a "slug") or escaped.

Removal can be done with the regex `/[^a-zA-Z0-9-._~]/`.

Escaping can be done with `encodeURIComponent()`.

If you wish to achieve an equivalent of ICONV transliteration (that is, turning `é` into `e` and `€` into `EUR`), you'll have to do your own, although you can leverage existing solutions and perhaps transform a transliteration table to JS format.
