You cut the significant statement at the top of the OP:

He has problems with invalid characters only running win32 console applications:
I changed the subject to hopefully better reflect the issue.

I am unsure where Cygwin 3.1.4 comes into Win32 applications - you have to use
the Windows codepage conversion routines.

You can only change input character sets on the fly; output character sets will
depend on mintty support of xterm-compatible character set support and switching
escape sequences; if you set up UCS16LE console output, Windows and mintty
should handle it.

Perhaps a better description of your environment, build tools, what you are
trying to do, what you expect as output, and what you are getting as output,
could help us better understand and help with the issue you see.
