Unicode characters appear in regular old vim in the terminal (iTerm), but not MacVim. Is there a way to get MacVim to handle Unicode characters appropriately. If it helps, I installed them using homebrew.
I grabbed these lines from the Vim Wiki:
if has("multi_byte")
if &termencoding == ""
let &termencoding = &encoding
endif
set encoding=utf-8
setglobal fileencoding=utf-8
"setglobal bomb
set fileencodings=ucs-bom,utf-8,latin1
endif
