You use the Hii protocol to add fonts.
Take a look at the RegisterFontPackage() function in
https://svn.code.sf.net/p/edk2/code/trunk/edk2/MdeModulePkg/Universal/Console/GraphicsConsoleDxe/GraphicsConsole.c
The Graphics Console driver carries the basic Roman fonts. This is the only
font available in the edk2 that I know about. But the infrastructure supports
adding more fonts.

Not sure about a doc? Localization is done via *.uni files. Here is an example
one from the shell
https://svn.code.sf.net/p/edk2/code/trunk/edk2/ShellPkg/Application/Shell/Shell.uni,
you can have multiple languages per token. The default EFI language is used.
The Shell uses the STRING_TOKEN() macro to access the string, and this is all
taken care of via the build system. For the most part the shell uses the
ShellPrintHiiEx(), so you can look that that to understand what Hii things are
going on.
How Hii works is documented in the UEFI spec, and I assume one of the build
specs talks about UNI files.
If you have a terminal connection that supports UTF-8 it would Just Work(tm),
assuming the terminal emulation program supported the font.
