#152 keyboard not found

[efa]

I use a custom keyboard mapping on Windows (this is valid for all applications, from command.com to notepad to remote SSH session) to type characters not available as default on keyboard using AltGr like on Linux, it is an Italian layout.
VcXsrv start without rise errors in the "Show log", but all X applications see a US layout as fallback.

The error that miss in the log is something like this:
(EE) Error loading keymap C:\Users\user\AppData\Local\Temp\server-0.xkm
(EE) XKB: Failed to load keymap. Loading default keymap instead.

If I select the standard Italian keyboard on Windows before start VcXsrv, all SSH console applications see the standard IT layout, so without extended characters, while X applications see the IT layout with extended characters. This is not ideal as all Windows applications and SSH consoles cannot send extended characters.

The start log is:

The extended characters are:
¬ ¹ ² ³ ¼ ½ ¬ { [ ] } ` ~ « »

console applications see the keyboard as so:

$ setxkbmap -v 10 -query

I made a try with those commands:

setxkbmap -layout it -variant mac -model macbook79 -option none -print > macbook79_map
xkbcomp -Ixkbdata -o server-0.xkm -xkm macbook79_map
copy server-0.xkm C:\Users\user\AppData\Local\Temp\server-0.xkm
start VcXsrv

AND

start VcXsrv
xkbcomp macbook79_map %DISPLAY%

with no luck, same results
