Encoding issue when muddling

[Dids]

There seems to be an encoding issue with special characters. See below for the original and muddled versions.

var corruptRegex = /`\w[¡¢£¤¥¦§¨©ª]`/g

l=/`\w[\u00a1\u00a2\u00a3\u00a4\u00a5\u00a6\u00a7\u00a8\u00a9\u00aa]`/g

I'm assuming it's just not handling utf-8 encoding/decoding properly?

EDIT: I guess it's more of a problem specific to hackmud, now that I think about it. The output from hackmud is as follows:

{retval:"PARSE ERROR my.script (line 0 char 261): cannot use \\u00XX or \\u{00XX} unicode identifiers in ascii range in scripts. Please use hex escape (\\xXX)",success:false}

As a temporary workaround, I made a tiny little Node.js utility for converting unicode characters to the hex escaped format.

escape.js:

#!/usr/bin/env node

process.argv.slice(2).forEach(inputCharacter => {
  console.log('Input character:', inputCharacter)
  console.log('Output character:', unicodeEscape(inputCharacter))
})

function unicodeEscape (str) {
  let result = ''
  let index = 0
  let charCode
  let escape
  while (!isNaN(charCode = str.charCodeAt(index++))) {
    escape = charCode.toString(16)
    result += charCode < 256
      ? '\\x' + (charCode > 15 ? '' : '0') + escape
      : '\\u' + ('0000' + escape).slice(-4)
  }
  return result
}

Usage:

> ./escape.js ¡¢£¤¥¦§¨©ª
Input character: ¡¢£¤¥¦§¨©ª
Output character: \xa1\xa2\xa3\xa4\xa5\xa6\xa7\xa8\xa9\xaa
