89 XConvertCase was copied from src/3rdparty/xkbcommon/src/keysym.c
90 The following code modifications were applied:
91
92 XConvertCase() was renamed to xkbcommon_XConvertCase(), to not confuse it
93 with Xlib's XConvertCase().
94
95 UCSConvertCase() was renamed to qt_UCSConvertCase() and function's body was
96 replaced to use Qt APIs for doing case conversion, which should give us better
97 results instead of using the less complete version from keysym.c
