Subject: [PATCH 1/3] Add g_option_context_parse_utf8
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch implements g_option_context_parse_utf()
along the lines of comment 63.

Contrary to the original patch (attachment 116044) I decided that
FILENAME arguments in UTF-8 mode should get the same treatment as in
non-UTF-8 mode, that is they get the exact argument string, and *not*
the string converted to filename encoding, since there's no guarantee it
will be representable in it.

Based on the patches by Tor Lillqvist and Krzysztof Kosiński.

Bug #522131.

- * @argv: a pointer to the array of command line arguments
- * @error: a return location for errors
- *
- * Parses the command line arguments, recognizing options

- * called.
- *
- * If the parsing is successful, any parsed arguments are
- * removed from the array and @argc and @argv are updated
- * accordingly. A '--' option is stripped from @argv
- * unless there are unparsed options before and after it,
- * or some of the options after it start with '-'. In case
- * of an error, @argc and @argv are left unmodified.
- *
- * If automatic <option>--help</option> support is enabled
- * (see g_option_context_set_help_enabled()), and the
- * @argv array contains one of the recognized help options,
- * this function will produce help output to stdout and
- * call <literal>exit (0)</literal>.
- *
- * Note that function depends on the
- * <link linkend="setlocale">current locale</link> for
- * automatic character set conversion of string and filename

+ * Parses the command line arguments, recognizing options
+ * which have been added to @context. A side-effect of
+ * calling this function is that g_set_prgname() will be
+ * called.
+ *
+ * If the parsing is successful, any parsed arguments are
+ * removed from the array and @argc and @argv are updated
+ * accordingly. A '--' option is stripped from @argv
+ * unless there are unparsed options before and after it,
+ * or some of the options after it start with '-'. In case
+ * of an error, @argc and @argv are left unmodified.
+ *
+ * If automatic <option>--help</option> support is enabled
+ * (see g_option_context_set_help_enabled()), and the
+ * @argv array contains one of the recognized help options,
+ * this function will produce help output to stdout and
+ * call <literal>exit (0)</literal>.
+ *
+ * Note that function depends on the
+ * <link linkend="setlocale">current locale</link> for
+ * automatic character set conversion of string and filename
+ * arguments.
+ *
+ * Return value: %TRUE if the parsing was successful,
+ *               %FALSE if an error occurred
