Thanks to a tweet from @resiak, I’ve learnt that ECMA-48 - Control Functions for Coded Character Sets provides some escape codes to diplay Fraktur!
According to wikipedia,
Fraktur [fʁakˈtuːɐ] is a calligraphic hand of the Latin alphabet and any of several blackletter typefaces derived from this hand. The blackletter lines are broken up – that is, their forms contain many angles when compared to the smooth curves of the Antiqua (common) typefaces modeled after antique Roman square capitals and Carolingian minuscule.
Not long ago, PragmataPro, the great monospace typeface I use every day got support for such characters.
I’ve spent few minutes to let terminology handle those escape codes.
If you follow the git version, you can try it like that:
echo "\033[20mabcdefghijklmnopqrstuvwxyz\n\033[0m"
echo "\033[20mABCDEFGHIJKLMNOPQRSTUVWXYZ\n\033[0m"
