* WC_DISCARDNS Discard nonspacing characters during conversion.

* WC_SEPCHARS Generate separate characters during conversion. This is the default conversion behavior.
|

* WC_DEFAULTCHAR Replace exceptions with the default character during conversion.
|

*
|

* lpWideCharStr
|

* Points to the wide-character string to be converted.
|

*
|

* cchWideChar
|

* Size (in WCHAR unit) of WideCharStr, or 0

* Points to the buffer to receive the translated string.

* cchMultiByte
|

* Specifies the size in bytes of the buffer pointed to by the

* lpMultiByteStr parameter. If this value is zero, the function

* returns the number of bytes required for the buffer.
|

* lpDefaultChar
|

* Points to the character used if a wide character cannot be

* represented in the specified code page. If this parameter is
|

* NULL, a system default value is used.
|

FIXME: ignored
|

* lpUsedDefaultChar
|

* Points to a flag that indicates whether a default character was used.

FIXME: allways set to FALSE.

*
|

*
|

*
|

* RETURN VALUE
|

* 0 on error; otherwise the number of bytes written
|

* in the lpMultiByteStr buffer. Or the number of
|
||||
* bytes needed for the lpMultiByteStr buffer if cchMultiByte is zero.
|
||||
*
|
||||
* NOTE
|
||||
* A raw converter for now. It just cuts off the upper 9 Bit.
|

* So the MBCS-string does not contain any LeadCharacters
