Use ibus-m17n as the default IME for Vietnamese
Summary
The current default input method for Vietnamese is ibus-bogo. This should change to the ibus-m17n input method “m17n:vi:telex - telex (m17n)”

Detailed Description
The current Fedora default input method ibus-bogo seems to be not actively maintained and it doesn't work on Gnome Wayland. The bug has been reported already in Fedora 30, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1690326
The ibus-m17n input method vi-telex.mim seems to do the same as ibus-bogo, see
https://bugzilla.redhat.com/show_bug.cgi?id=1690326#c12
Using vi-telex.mim via ibus-m17n seems to behave exactly like ibus-bogo.
If ibus-bogo offers no additional benefit, it is probably better to use ibus-m17n with vi-telex as the default input method for Vietnamese. ibus-m17n has to be maintained anyway. Therefore, this saves the effort of fixing the unmaintained ibus-bogo.
Feedback
Benefit to Fedora
Vietnamese input works again on Gnome-Wayland. Currently with ibus-bogo it is broken.
Scope
- Proposal owners:
- update default IME in comps @input methods
- update langpacks-vi to use ibus-m17n and m17n-db
- the langtable package has data about default input methods. Change this data.
- Change default input method in
libgnome-desktop/default-input-sources.h
Here are the changes for ibus-anthy requested by Takao Fujiwara, I need to request similar changes for changing from ibus-bogo as the default to ibus-m17n:
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3430
https://gitlab.gnome.org/fujiwarat/gnome-desktop/-/commit/04ad3737d5d1b66ede1b4fbd9672ba8c373c06e8
- Other developers: gnome-desktop3 for default vi_VN input method
- Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)
- Policies and guidelines: N/A (not a System Wide Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with Objectives:
Upgrade/compatibility impact
The package installed by default will change from ibus-bogo to the packages ibus-m17n and m17n-db for an installation in Vietnamese.
How To Test
Install Fedora in Vietnamese and check that the default input method is vi-telex with ibus-m17n.
User Experience
- There should be very little difference in typing Vietnamese as ibus-bogo and ibus-m17n with vi-telex.mim behave the same.
- The setup tool looks a little different.
- Package sizes and dependent packages are different.
- Memory usage is different.
Dependencies
ibus-m17n and m17n-db
- comps has to be updated
- gnome-desktop3 has to be updated
