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