The Vim help says &guifont is global, so I don't believe different
fonts can be used in separate buffers.

I'd recommend you just get a good unifont that has all the characters
you need. I suggest Andale Mono or Bitstream Vera Sans Mono.
(Obviously, if you are dealing with existing files some conversion
would be required... see :help charconvert.)

Essentially, Vim has two distinct options, see

  :help encoding
  :help fileencoding

The first relates to Vim's internal encoding, that used to interpret
key presses, scripts used by menus, etc. The second relates to the
file itself, the actual bits stored on disk. It is theoretically
possible to have Vim use one encoding (UTF-8) while working in a file
of another encoding (Latin) but you then have to be extremely careful
of making key presses which insert characters that don't fit the
file's encoding.

As a mono-lingual, non-mathematically or scientifically inclined
English speaker, I've thus far escaped educating myself beyond what
encoding options work for me and tend to favor simplicity by keeping
both encoding and fileencoding the same. But there are others here who
far better versed on this Vim capability and might be able to get you
past my overly simplistic explanation, hopefully they will chime in.

Let us know if there is something specifically in Cream that prevents
you from using any Vim capabilities, we want to avoid that.
