No character is output when using allchars sequences in GTK+ applications. I tried with Pidgin and Gimp using GTK+ v2.16.0 (glib 2.20.0).
This is a real showstopper for me. :-(
You seem to have CSS turned off.
Please don't fill out this field.
You can work around it by composing the characters in another application and then copy-n-paste, which works as expected.
Looking forward to a fix.
