53 XConvertCase was copied from src/3rdparty/xkbcommon/src/keysym.c
54 The following code modifications were applied:
55
56 XConvertCase() was renamed to xkbcommon_XConvertCase(), to not confuse it
57 with Xlib's XConvertCase().
58
59 UCSConvertCase() was renamed to qt_UCSConvertCase() and function's body was
60 replaced to use Qt APIs for doing case conversion, which should give us better
61 results instead of using the less complete version from keysym.c
