switching to any other than English keyboard layout is not handled correctly anymore on the prompt at minimum

[Ariel Burbaickij]

Hello Cygwin,
I tried to find some files from the command line prompt which are named
using various non-Latin (Russian, Hebrew, Arabic) and non-default Latin
(German) layouts under Windows 10 Enterprise using recent cygwin version
and the outcome is that instead of representing letters I see control
characters of the type: \263\320\321  (Unicode numeric value of the
letters?). Any ideas what happens here and how correct functionality can be
restored?

Kind Regards
