Hi!

I'm not too familiar with the way Windows handles non-ASCII characters
in operating system calls, but I assume that what gets passed to the C
library runtime functions like fopen(3), etc. assumes a particular encoding.

>From a quick glance at the Windows docs[1] it seems one needs to use
"_fwopen" with a wchar_t string argument to pass extended characters.
What you could do is to use the FFI to call "_fwopen" with a suitably converted
argument string and the use "open-input-file*" to convert it into a Scheme port
(Just ask if you need help with this).

Sorry, if this is not overly helpful. We are currently in the process of 
improving
the unicode support for the next major version of CHICKEN.
