Gawk understands and uses any LC_* and LANG variables that Posix
requires, if Gawk uses glibc.  Otherwise you depend on the particular
library, and no one says that all of them use the same collation order
that glibc does, for the same locale.

You assume that for every encoding in an Info document every user will
have the corresponding locale installed and supported by the local
libc?

(And it isn't only the language, it's also the codeset -- which I'm
sure you know.)
