Re: outputting Unicode to console

Hi Henry!

I need to use low-level I/O such as write() to print some messages to stdout. However, when the program is compiled to use wide chars the printed output is correspondingly wide!

As long as you only want to display ASCII chars, I would not recommend to use UNICODE in console apps...

If you want to display other chars (like chineese) you need to be aware of the following:
- your console must have a appropriate font which can display the chars (glyphs); the normal (default) font is not able to do this.
- if you use functions like "wprintf/wcout", it is not possible to display unicode-charachers (see: wprintf/wcout has no UNICODE support http://blog.kalmbachnet.de/?postid=23 http://blog.kalmbachnet.de/?postid=5)
- if you use native functions like write, then this uses internally WriteFile with which is also not possible to output unicode characters...
- to output unicode characters you need to use WriteConsoleW (http://msdn.microsoft.com/library/en-us/dllproc/base/writeconsole.asp)



Do I have to go through the WideCharToMultiByte() process for each message or is there a cleaner solution? 

If you just want to display ANSI/ASCII-characters this one solution...

An other would be:
<code>
wchar_t wbuf[] = L"HI THERE\n";
printf("%S", wbuf);
</code>
