Firmware 3.19.5613 replaces the font file Ryumin.otf with KBJ-TsukuMinPr6N-RB.ttf, and changes in the database the reading font family "A-OTF Ryumin Pr6N R-KL" to "KBJ-TsukuMin Pr6N RB". If this creates problems for you (as it does for some users) you might try the following:
- 1) Extract Ryumin.otf from an older FW package and copy it to /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts
- 2) run the uploaded script tsukuMin2ryumin.sh
at 1): You can do this for instance by using the update mechanism (KoboRoot.tgz), or by the KSM function "copy sysmirror to sys.sh" (cf.
this post)
at 2): You can copy the script for instance into .adds/kbmenu_user/scripts, and run it by selecting "user scripts" > "tsukuMin2ryumin.sh".
Edit: You can back up your database by selecting "tools" > "back up and restore" > "restore" > "restore db.sh"
