when compiling: unsupported char 0xc2

[Markku Sukanen]

Got a "little" problem with source code and the characters/letters used 
in it...  And would like to know how to rectify this:

I'm usually using 'vim' (or 'gvim') for editing source codes, but now as 
learning D as new language, came against a problem with '|' (the vertical 
bar) in source code.  Whenever dmd encounters a '|' in code (outside 
string literals), it errors out with i.e.:

    ...somesource.d(84): unsupported char 0xc2

So, for now, have had to put i.e. "if (a == 2 || b == 3)" to separate if/
else's.
