Subject: [PATCH] Fix build with GCC 14 and modern glib: const correctness and
 deprecated API

- Use 'const gchar*' for result of g_utf8_next_char() to satisfy GCC 14's stricter const rules
- Remove incorrect g_free() on non-allocated pointer from g_utf8_next_char()
- Replace deprecated g_pattern_match_string() with g_pattern_spec_match_string()
