I did a fresh install of Debian Jessie last week and realized that this issue seems to be solved in grub2 2.00-22.
Some time after I reported this bug I found out that the workaround mentioned in message #12 of bug 617196 [1] worked for me. Since then I didn't check if this is still a problem. This time I used LVM within an encrypted partition again, so /boot was the only partition available at boot time (same as in September 2011 when I reported this bug). As of now it seems the font which was missing before (unicode.pf2) is now installed not only in /boot/grub/ but also in /boot/grub/fonts/.
