I'll also note that we used to have file-ids and revision-ids as Unicode
strings in memory, but intentionally switched back to 8-bit strings.
Mostly for performance/memory consumption. (Default Unicode on most
Unixes is UCS-4, which means we bloated every revision-id and file-id by
approximately 4x. And when you have 100,000+ of them, that gets pretty big)
