Google can:
<http://translate.google.com/translate?hl=en&sl=ja&u=http://www.okisoft.co.jp/esc/utf8-cygwin/download.html>.

Also,
<http://translate.google.com/translate?hl=en&u=http://www.okisoft.co.jp/esc/cygwin-20.html>
describes the architecture of the changes.

I've looked at the sources (which are branched off 1.5.19-4).  Basically,
there's a 930-line patch, most of which is new.  FWICS, it may not cover
all places where Unicode conversion may be needed (in particular, sending
Unicode through a textmode pipe will very likely fail spectacularly).  It
also looks like some places are kludged specifically for the Japanese
section of Unicode.  But it's an interesting first approximation.

There are also patches for cygstart.

I wonder why the author chose to do a branch, rather than submit the patch
back to Cygwin?  It's also unclear what current functionality it breaks.
I guess at some point the author would need to be Cc'd on this thread...
