    cygwin: select: use UNICODE console functions
    
    For historical reasons peek_console was calling the functions
    PeekConsoleInputA and ReadConsoleInputA.  However, these functions are
    not working correctly under at least codepage 65001 (UTF-8) on systems
    prior to Windows 10.
    
    Use PeekConsoleInputW and ReadConsoleInputW instead, which work
    correctly under all systems and all codepages.
