Ubuntu – What was the default font for Ubuntu 11.04

Basically what you want to do is use the range operator to limit the characters that your new grub font contains. If you don't use the range operator then you're going to get all the glyphs including the erroneous or incorrect box elements from your target font.

For example:

grub-mkfont -s 16 --range=0x0-0x7f -o /boot/grub/grubfont.pf2 font.tty

Will generate a font with only ASCII characters, anything your font doesn't have should decay gracefully to the default font so boxes and arrows should come from the default. Please see this website for further information:

The default font of grub2 in 12.04 is unicode.pf2. Check this command

grep -n font /boot/grub/grub.cfg

It is described in 45th line in grub.cfg file. The location of the font is /usr/share/grub/unicode.pf2.

Update to include information from OP's comment:

OP wrote in a later comment,

In Grub Customizer on the right side there is a little red minus sign that removes the custom font. click that and hit save and boom back to the default font
