I have always relied on locale(1) for this stuff. Why do we need to
override the locale in this script?
Note that even if locale(1) is installed, there may be no @euro locale
provided, such as on my laptop:
$ locale -a | fmt
C POSIX en_AU en_AU.iso88591 en_AU.utf8
FWIW, I have a /usr/bin/locale on SunOS 5.8 (Last change: 20 Dec 1996).
indicates it was part of the 2003 POSIX.1 spec.
