- *	Convert between UTF-8 and Unicode when running Windows NT or the
- *	current ANSI code page when running Windows 95.
- *
- *	On Mac, Unix, and Windows 95, all strings exchanged between Tcl and
- *	the OS are "char" oriented. We need only one Tcl_Encoding to convert
- *	between UTF-8 and the system's native encoding. We use NULL to
- *	represent that encoding.
- *
- *	On NT, some strings exchanged between Tcl and the OS are "char"
- *	oriented, while others are in Unicode. We need two Tcl_Encoding APIs
- *	depending on whether we are targeting a "char" or Unicode interface.
- *
- *	Calling Tcl_UtfToExternal() or Tcl_ExternalToUtf() with an encoding of
- *	NULL should always used to convert between UTF-8 and the system's
- *	"char" oriented encoding. The following two functions are used in
- *	Windows-specific code to convert between UTF-8 and Unicode strings
- *	(NT) or "char" strings(95). This saves you the trouble of writing the
- *	following type of fragment over and over:
- *
- *		if (running NT) {
- *		    encoding <- Tcl_GetEncoding("unicode");
- *		    nativeBuffer <- UtfToExternal(encoding, utfBuffer);
- *		    Tcl_FreeEncoding(encoding);
- *		} else {
- *		    nativeBuffer <- UtfToExternal(NULL, utfBuffer);
- *		}
- *
- *	By convention, in Windows a TCHAR is a character in the ANSI code page
- *	on Windows 95, a Unicode character on Windows NT. If you plan on
- *	targeting a Unicode interfaces when running on NT and a "char"
- *	oriented interface while running on 95, these functions should be
- *	used. If you plan on targetting the same "char" oriented function on
- *	both 95 and NT, use Tcl_UtfToExternal() with an encoding of NULL.
- *
- * Results:
- *	The result is a pointer to the string in the desired target encoding.
- *	Storage for the result string is allocated in dsPtr; the caller must
- *	call Tcl_DStringFree() when the result is no longer needed.
