The problem here is to map Qt4 keys to LibVLC keys. Qt4 refers to alphabetic
keys with their ISO-8859-1 (or Unicode) upper-case code point, whereas LibVLC
refers to them with their lower-case.
Changing the LibVLC convention to that of Qt4 would not solve the problem. X11
also uses the lower-case convention as LibVLC does. Hence, we'd only move the
problem from the Qt4 plugin to the XCB/window plugin.
So we need to map the upper-case characters to lower-case. As far as only
Latin-1 is concerned, a static mapping might actually be better than
towlower() - I was just being lazy when I wrote that code. Afterall, there is
no reason why the key mapping would work or not work depending on the systel
