Why would font not matter? Unicode is the abstract definition 
of all characters right? From that we map the abstract 
character to a code page/set, which gives real values for an
abstract character. From that code page we then visually display 
the "real value" based on the font. If that font does
not have a glyph for a specific character page (or a different
glyph) then that is a problem and not related encoding. 

Unicode->code page->font

This is a mismatched translation between code pages; not
font related but is instead one abstraction "level" up.
