\fBTcl_ExternalToUtf\fR.
.PP
\fBTcl_WinUtfToTChar\fR and \fBTcl_WinTCharToUtf\fR are
Windows-only convenience
functions for converting between UTF-8 and Windows strings
based on the TCHAR type which is by convention
a Unicode character on Windows NT.
These functions are essentially wrappers around
\fBTcl_UtfToExternalDString\fR and
\fBTcl_ExternalToUtfDString\fR that convert to and from the
Unicode encoding.
.PP
\fBTcl_GetEncodingName\fR is roughly the inverse of \fBTcl_GetEncoding\fR.
Given an \fIencoding\fR, the return value is the \fIname\fR argument that
was used to create the encoding.  The string returned by
\fBTcl_GetEncodingName\fR is only guaranteed to persist until the
\fIencoding\fR is deleted.  The caller must not modify this string.

 *
 *	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.
