Entering Unicode characters with code points broken

[Gunnar Hjalmarsson]

On an updated lunar, following this instruction:

https://help.ubuntu.com/stable/ubuntu-help/tips-specialchars.html#ctrlshiftu

no longer works. If I press for instance

Ctrl+Shift+U followed by 2014

I see u2014 (underlined) on the screen. But it's not replaced with the expected character (in this case an Em Dash) when I confirm with Space or Enter — it just disappears.

Happens in both x11 and wayland sessions.

The same problem exists on KDE. So this looks more like an issue in ibus then in gnome-shell.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Yes, Heinrich, on the surface this seems to be an ibus issue. But I think the root cause lies in some package which ibus is built with.

If I downgrade to the binaries built by ibus 1.5.28-1 on February 23, using code points works fine. In 1.5.28-2 two upstream commits were added as patches, but if I now build ibus with those patches disabled, it doesn't help. A no-change rebuild does not help either.

Maybe glib is the culprit? ibus 1.5.28-1 was built with glib 2.74.

[Heinrich Schuchardt (xypron)]

The problem is reproducible on amd64, arm64, riscv64.

[Gunnar Hjalmarsson (gunnarhj)]

If I install ibus 1.5.28-2 from experimental on Debian, there is no code point issue. While the source is identical with 1.5.28-2 on Ubuntu, the binaries on Debian were built with older versions of some libraries.

I'm not sure that the problem lies in glib. It's simply my intuition. ;)

[Gunnar Hjalmarsson (gunnarhj)]

This is under control now. An upstream ibus commit fixes it (see discussion at upstream issue).

Fix uploaded to Debian experimental.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ibus - 1.5.28-3
