#50 Support output of all kinds of Unicode character to a Windows console
The Unicode characters that can be printed on a cmd.exe console on Windows through clisp is limited by the *TERMINAL-ENCODING*.
1) The *TERMINAL-ENCODING* is determined from GetOEMCP(). This does not consider the possibility of "chcp 65001". So, need to use GetConsoleOutputCP() instead of GetOEMCP().
2) There are 3 ways to output arbitrary Unicode characters (or at least Unicode BMP characters) to a console.

2.1) Instead of WriteFile and WriteConsole with a char* argument, use WriteConsoleW with a wchar_t* argument.
2.2) Use _setmode(1, _O_U16TEXT). Pass a char* argument with text in aligned UTF-16LE encoding.
2.3) Use _setmode(1, _O_U8TEXT). Pass a char* argument with text in UTF-8 encoding.
