So what is FONT_MAP for?

Check the setfont(8) manpage.

Thanks. So if I understand correctly, it is useful for programs that output 8 bit characters that are not valid UTF-8 sequences and serves to convert their output into valid unicode for display, right?

No, some console fonts don't have a Unicode map, so they're essentially an index -> glyph file where index is from 0-255. A unicode map adds a "Unicode Code Point -> index" mapping.

Most fonts in /usr/share/kbd/consolefonts should have bult-in maps (haven't checked though). For those that don't have it, there's the -m option in setfont or FONT_MAP.

Without an unicode map, you must make sure the loaded font has the same layout as the charset you're using. Without the unicode map you can't use utf8

Now I'm confused. According to setfont(8), there are two kinds of maps (not counting the keymap): the console map (option -m) and the unicode font map (option -u). What you describes appears to be the unicode font map but that still leaves the other one.

BTW, which does FONT_MAP refer to? I tried to grep through /etc to see how it is used in the initscripts, but this only shows the vconsole.conf entry...

If you look at "man vconsole.conf", you see there's both FONT_MAP and FONT_UNIMAP. FONT_MAP refers to the console map, not the unicode font map.
