Pretty much. It's a big-endian representation of a 32-bit integer
as a character string. It's what you get when you don't have iconv
or iconv fails and the locale isn't UTF-8. It may not be useful,
but it's predictable. If we have a locale the system doesn't know
about or can't translate, there's not a lot we can do.
