Cannot enter character via shift-ctrl-u shortcut

[Jeroen Hoek]

In most Gnome applications I can use shift-ctrl-u to directly enter a character via its Unicode codepoint. So, for example, to enter the character € via this method, one does:

shift-ctrl-u 2 0 A C enter

This works in gedit and gnome-terminal today.

I use this often in gucharmap when dealing with a character I don't recognize, and can't easily directly copy from the source. Since updating to Ubuntu 16.04, the gucharmap version shipped with Ubuntu has started to ignore the shift-ctrl-u shortcut in the search text field.

Upstream reports that this appears to be a Ubuntu specific issue:
