Thank you very much!
I tried this holydays to dive into libX11 code, also configured the
key on my VirtualBox. I didn't understood though what does the
function «bool _XimLocalFilter(Display*, Window, XEvent*, XPointer)»
of the «imLcFlt.c» except that it is somehow filters every keypress. I
found it is called every time when I am press a key. It would be great
if someone accidentally leaved in the header file a description of a
function 😂
Anyway, right now I stumbled upon a strange fact that when I am
replace an original «» with a newly compiled one, the
compose key just stops working. I didn't changed anything except that
configured compilation with «-g3» added to CFLAGS and CPPFLAGS. Have
anybody an idea what could cause it?
