Summary

This recommended default input method for Vietnamese will be changed from ibus-bogo to ibus-unikey.

Owner

Name: Mike Fabian
Email: <mfabian@redhat.com>

Current status

Targeted release: Fedora 34
Last updated: 2021-02-25
FESCo issue: #2527
Tracker bug: #1913431
Release notes tracker: #625

Detailed Description

The current Fedora recommended Vietnamese input method ibus-bogo seems not actively maintained, and doesn't work well currently with GNOME Wayland for some time.

Since the ibus-unikey input method seems to work better under Wayland and provides similar functionality, it is now recommended input method and installed for Vietnamese users.

Feedback

Benefit to Fedora

Provides Vietnamese input that should work across desktops including GNOME Wayland.

ibus-unikey also has less dependencies when installed under GNOME.

Scope

Proposal owners:
- update langpacks-vi to use ibus-unikey [done]

Release engineering: #9907

Policies and guidelines: N/A (not a System Wide Change)

Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Upgrades are not affected, and ibus-unikey should be reasonably compatible with ibus-bogo for Vietnamese input.

How To Test

1. After doing a Vietnamese installation of Fedora and check that ibus-unikey is installed. The Unikey input method should be available:

$ ibus list-engine | grep Unikey
  Unikey - Unikey

2. Then it should be possible to add the Vietnamese Unikey input method in gnome-control-center.

3. Select Unikey in the input sources menu list in the GNOME panel.

4. Start gedit and type: “Khoong cos gif quis hown ddoocj laapj tuwj do”.

5. You should get the result: “Không có gì quí hơn độc lập tự do”.

The following screenshots show how to add the ibus-unikey input method and do these tests. ibus-unikey:

How to use the ibus-unikey input method.

User Experience

Vietnamese users should not notice much difference in typing Vietnamese with ibus-unikey compared to ibus-bogo, except that Unikey works much better under Wayland.

The setup tool looks a little different: ibus-unikey does not depend on Qt.

Dependencies

None

Contingency Plan

None needed really, but we change back to ibus-bogo.

Contingency mechanism: Revert langpacks-vi to ibus-bogo
Contingency deadline: Beta release
Blocks release? No
Blocks product? None
