Fixed #9212: Added code to check the xgettext version, and if it is lower than...

            message = "usage: make-messages.py -l <language>\n   or: make-messages.py -a\n"

        raise CommandError(message)

    # xgettext versions prior to 0.15 assumed Python source files were encoded

    # in iso-8859-1, and produce utf-8 output.  In the case where xgettext is

    # given utf-8 input (required for Django files with non-ASCII characters),

    # this results in a utf-8 re-encoding of the original utf-8 that needs to be

    # undone to restore the original utf-8.  So we check the xgettext version

    # here once and set a flag to remember if a utf-8 decoding needs to be done

    # on xgettext's output for Python files.  We default to assuming this isn't

    # necessary if we run into any trouble determining the version.

    xgettext_reencodes_utf8 = False

    (stdin, stdout, stderr) = os.popen3('xgettext --version', 't')

    match = re.search(r'(?P<major>\d+)\.(?P<minor>\d+)', stdout.read())

    if match:

        xversion = (int(match.group('major')), int(match.group('minor')))

        if xversion < (0, 15):

            xgettext_reencodes_utf8 = True

    languages = []

    if locale is not None:

        languages.append(locale)

                errors = stderr.read()

                if errors:

                    raise CommandError("errors happened while running xgettext on %s\n%s" % (file, errors))

                if xgettext_reencodes_utf8:

                    msgs = msgs.decode('utf-8').encode('iso-8859-1')

                if thefile != file:

                    old = '#: '+os.path.join(dirpath, thefile)[2:]

                    new = '#: '+os.path.join(dirpath, file)[2:]

      * In the ``System variables`` list, click ``Path``, click ``Edit``

      * Add ``;C:\Program Files\gettext-utils\bin`` at the end of the

        ``Variable value`` field

You may also use ``gettext`` binaries you have obtained elsewhere, so long as 

the ``xgettext --version`` command works properly. Some version 0.14.4 binaries

have been found to not support this command. Do not attempt to use Django 

translation utilities with a ``gettext`` package if the command ``xgettext

--version`` entered at a Windows command prompt causes a popup window saying

"xgettext.exe has generated errors and will be closed by Windows".
