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.
