Description of problem:

Unless charset is specified in config file or with --display-charset argument, gpg2 output incorrect (and different from the gpg output) for utf-8 encoded strings.

Version-Release number of selected component (if applicable):
gnupg2-2.0.9-2.fc9.i386


Steps to Reproduce:

$ locale charmap
UTF-8
$ gpg -vvv pub.asc 2>&1 |head -1
gpg: using character set `utf-8'
$ gpg2 -vvv pub.asc 2>&1 |head -1
gpg: using character set `iso-8859-1'

Additional info:

The reason seems to be that gpg.c calls init_common_subsystems() before initializing the locale via i18n_init() or a setlocale() call. Therefore detects as ANSI_X3.4-1968 (i.e us-ascii) and uses iso-8859-1 as fallback.
