RFC5987 "value-chars" encode/decode
Great for HTTP header fields such as the "filename" of a "Content-Disposition".Lightweight: 16 lines
const {encode, decode} = require('rfc5987-value-chars')
decode(encode(filename))Largely inspired by examples at: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/GlobalObjects/encodeURIComponent
