I use a custom keyboard map (via xmodmap) to type some decorative UTF8 characters quickly. After upgrading KDE to 15.08, characters typed this way don't show up in some applications at all.

Reproducible: Always

Steps to Reproduce:
The following shell script allows to type the "Fallen leaf" character (unicode character 0x1F342) by pressing AltGr+"L":

echo "keycode  46 = l L l L U1F342 Lstroke lstroke" > /tmp/.leaf-xmodmap
xmodmap  /tmp/.leaf-xmodmap
rm  /tmp/.leafdoc-xmodmap

Run it in a console, then press AltGr+L while in different applications (kate, konqueror, konsole) and places (katepart, filepicker, etc)


Actual Results:  
In some applications/kparts, the typed character doesn't show up at all. Most notably, I cannot type the character in a katepart in Kate, but I can type it in a konsolepart in the same Kate window.

Expected Results:  
Character should always appear when typed.

I'm using KDE vesion 15.08.1, ,compiled against KDE frameworks 5.14.0 and Qt 5.4.2 (from Debian unstable packages).
