Current status
- Targeted release: Fedora 34
- Last updated: 2021-01-15
- FESCo issue: #2542
- Tracker bug: <will be assigned by the Wrangler>
- Release notes tracker: <will be assigned by the Wrangler>
Detailed Description
Currently IBus disables the emoji and Unicode features in some system users likes gdm, liveuser, gnome-initial-setup not to exhaust the limited memory usage with LiveDVD. The emoji data requires about 10MB and the Unicode data requires about 15MB and the total 25MB is required roughly to show the tables. The Fedora testers ask to test the emoji feature and Unicode feature in LiveDVD and the next IBus will use mmap to be available the emoji and Unicode data with liveuser.
Feedback
Fedora I18N testers asks to test the emoji and Unicode data without installing Fedora to disc.
Benefit to Fedora
IBus will reduce the physical memory usage to load the emoji and Unicode data per user.
