Bug#351786: libstdc++6: bad thousand separator with fr_FR.UTF-8

[Benoît Dejean <benoit@placenet.org>]

Package: libstdc++6
Version: 4.0.2-7
Severity: normal
Tags: l10n

Summary : outputs weird caracters instead of proper thousand
separator.

Consider the attached simple program.  It ouputs a wrong thousand
separator using fr_FR.UTF-8 (i haven't tested other locales). (French
thousand separator should be '.' (dot)) Moreover, the current thousand
separator is weird : it outputs a '\xc2'. '\xc2' looks like the
beginning of a multibyte UTF-8 char.

I'm using belocs-locales.
