 vote and i was told that we don't use raw bytes anymore.

 Directory documents never contain raw bytes.

 > Searching for "base64" in dir-spec.txt, gives several results, though i
 couldn't find a paragraph that would confirm that.

 Directory documents only contain printing ASCII characters:

 Although we allow some other text encodings in the contact and platform
 lines.
