Automate transcoding of userComment string value

[nhoizey]

When I activate userComment extraction with userComment: true, I get an object like this (shortened):

{
  "userComment": {
    "0": 65,
    "1": 83,
    "2": 67,
    "3": 73,
    "4": 73,
    "5": 0,
    "6": 0,
    "7": 0,
    "8": 80,
    "9": 104,
    "10": 111,
    "11": 116,
    "12": 111,
    "13": 32,
    "14": 111,
    "15": 102,
    "16": 32,
    "17": 116,
    "18": 104,
    "19": 114,
    "20": 101,
    "20": 101
  }
}

This is a sequence of character codes, which we can translate to a string, for example with this code:

Object.values(output.userComment)
  .map((char) => String.fromCharCode(char))
  .join('');

Here, we get the string ASCII\0\0\0Photo of three.

It would be nice if:

• we did get the string strait from exifr
• the encoding part in the beginning would be removed
