Some corrections and more observations: * /boot/grub/unicode.pf2 will be (wrongly?) generated (copied) after "dpkg- reconfigure grub-efi-amd64", not "dpkg-reconfigure grub-common". * Grub2 in Debian Stable (Stretch) provides the *wrong* unicode.pf2 file (1.3MiB) while grub2 in Debian Testing/Unstable provides the good unicode.pf2 file (2.3MiB). A stable-updates might be necessary later. Now I believe there are two problems to be fixed in Stretch and one problem in Buster/Sid: 1. grub-common should provide unicode.pf2 with (somehow) better CJK character support (bug in Stretch only) 2. configuration in grub-efi-amd64 (and all other similar processes) may should install unicode.pf2 file into /boot/grub/fonts/ directory, not /boot/grub/ directory. (bug in both Stretch and Testing/Unstable) Regards, Boyuan Yang
