[Proj] Unicode

[support.mn at elisanet.fi]

It is clear that sometime in the future Unicode will be
the de facto world standard character set. Proj-4 can
live very well without Unicode characters, since it is
more a definition language. It is like the C programming
language. The language it self does not include special
characters, but most modern systems can handle Unicode
files and characters in comments and strings for example.

It is more to allow Unicode systems to feed data to proj-4
but still limit the basic definition character set to the 7-bit
ascii (or whatever). Proj-4 would just pass through all
special characters.

The great idea is that proj-4 would not crash with Unicoded
characters or files.
