I got some interesting results from investigations. If we try to locate unicode.pf2, we should get: # locate unicode.pf2 /boot/grub/unicode.pf2 /boot/grub/fonts/unicode.pf2 /usr/share/grub/unicode.pf2 It's strange that we have *two* font files in /boot/grub/. The first one has a size of 1.4MiB while the second one has the size of 2.3MiB. Here are some tests: * Remove /boot/grub/fonts/unicode.pf2: nothing happens. * Remove /boot/grub/unicode.pf2: grub2 immediately fallbacks back to English and black-and-blue-colored theme. * Run "dpkg-reconfigure grub-common: /boot/grub/unicode.pf2 copied from /usr/ share/grub/unicode.pf2; /boot/grub/fonts/unicode.pf2 not touched. Well now I suggests that the path /boot/grub/unicode.pf2 is a mistake and should not exists. I will make further tests with fresh-installed Debian Testing in VMs later. -- Regards, Boyuan Yang
