  Improved tests related to keysyms - Add a keymap test with decimal and hexadecimal keysyms. - Reorganize code in `test/keysym.c` by parsing type: name, Unicode and hexadecimal. - Add more tests for edge cases. In particular: - test decimal format (currently not supported); - test the Unicode and hexadecimal ranges more thoroughly; - test with wrong case without the XKB_KEYSYM_CASE_INSENSITIVE flag; - test surrounding spaces. - Document the tests.
