But for the terminal? Try Ctrl-Alt-F1 to drop out of X and into a Linux/BSD terminal, and runghc on a file containing,

I get a bunch of grey question marks.
By default, Ctrl+Alt+F1 takes you to a "virtual console," which uses a framebuffer with very limited memory. Console fonts are limited to 256 glyphs, or 512 glyphs with fewer colors, which is too few glyphs for a proper CJK Unicode font. (**tangent below**) This issue applies to all Unicode software; it is not specific to Haskell. Cheers, Travis **tangent** It is possible to use Unicode outside of X with other software. For example, fbterm is a terminal emulator that selects fonts with fontconfig and renders them using freetype2, making the usual X fonts available for use.
