a pointer to the command line arguments (which must be in UTF-8 on Windows). Starting with GLib 2.62, @arguments can be %NULL, which matches g_option_context_parse().
%TRUE if the parsing was successful, %FALSE if an error occurred
GException on failure.

Parses the command line arguments.
This function is similar to g_option_context_parse() except that it respects the normal memory rules when dealing with a strv instead of assuming that the passed-in array is the argv of the main function.
In particular, strings that are removed from the arguments list will be freed using g_free().
On Windows, the strings are expected to be in UTF-8. This is in contrast to g_option_context_parse() which expects them to be in the system codepage, which is how they are passed as @argv to main(). See g_win32_get_command_line() for a solution.
This function is useful if you are trying to use #GOptionContext with #GApplication.
