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
