\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.
.PP

As part of processing each command, \fBTcl_Eval\fR initializes
\fIinterp->result\fR
and \fIinterp->freeProc\fR just before calling the command procedure for
the command.  The \fIfreeProc\fR field will be initialized to zero,
and \fIinterp->result\fR will point to an empty string.  Commands that
do not return any value can simply leave the fields alone.
Furthermore, the empty string pointed to by \fIresult\fR is actually
part of an array of \fBTCL_RESULT_SIZE\fR characters (approximately 200).
If a command wishes to return a short string, it can simply copy
it to the area pointed to by \fIinterp->result\fR.  Or, it can use
the sprintf procedure to generate a short result string at the location
pointed to by \fIinterp->result\fR.
.PP
It is a general convention in Tcl-based applications that the result
of an interpreter is normally in the initialized state described

# to preserve backwards compatibility.
