On NT 4 and Win 2000 the code page can also be specified as CP_UTF7
and CP_UTF8, in which case the UTF-16 is converted to a sequence of
UTF-7 or UTF-8, so this function is also very usable in fully Unicode

For "normal" code pages (and I think this applies to all Win32
platforms), the code page must be installed, i.e. the CP_*.nls files
must be in the system32 subdirectory and registry keys must be
pointing to these files. Usually this code page installation is done
from the control panel.

Please remember to use the Lucida Console font in that window, since
the raster font seems to be hardwired for the OEM code page.
