The problem is on a machine (hearinafter known as machine 1) running
Gnome + GTK+2.12.9 ctrl-shift-u nothing is displayed then 5 while
holding the ctrl-shift gives %, this was with Geany 0.18 and head
Tried it on a machine (hearinafter known as machine 2) with Xfce +
GTK+2.12.9 and it works, ctrl-shift-u gives an underlined u and
ctrl-shift 5 an underlined 5 etc until a non-ctrl-shift character when
it enters the unicode character this was with Geany r3994 (pre 0.18 I
That seems to indicate that:
1. it isn't a Geany problem
2. it isn't a GTK problem
3. it *is* a Gnome problem, but how Gnome interferes I don't understand
But !!! Having written that I've read a little used piece of GTK doc,
IMContexts. This defines how input methods work. For an entry widget
the context menu gives you a choice of input methods.
Using the find entry on the toolbar as an example I found that machine
1 has the input method set to X input method and machine 2 has it set
Setting machine 1 to default makes it work like machine 2, that is
unicode entry works in the entry widget as described.
Unfortunately there is no way of setting the input method for the
editor window that I could find. Any ideas?

True, but at least I could enter characters into the test file so I
could go on testing my code.
