Support unicode character entry (CTRL SHIFT u, code, ENTER) in Linux
This was reported in #12300: MuseJazz Font is missing european diacritical characters:
I'm trying this on Linux (openSuse) with 1.1 during text entry, for example in the song title:
The CTRL+SHIFT u, code, ENTER method doesn't work.
Here in Firefox it works: CTRL+SHIFT u, then 0041 ENTER gives A, or 00A5 gives ¥.
COMPOSE ` a will enter an à, ss will enter ß, so that works.
Can someone please test with the latest trunk on Linux.
