GB2312 is incompatible with the portable codeset, i.e. ASCII, and we
can't handle that in Cygwin.  The underlying code translates GB2312
into codepage 936 which defines GBK.  So GB2312 in Cygwin is actually GBK.

Somebody would have to provide code...

The newlib code should support it.  Cygwin couldn't due to some
incompatibility problem.
