 source buffer is long enough such that this routine does not run off the
 end and dereference non-existent or random memory; if the source buffer
 is known to be null-terminated, this will not happen.  If the input is
+a byte in the range 0x80 - 0x9F, \fBTcl_UtfToUniChar\fR assumes the

 not in proper UTF-8 format, \fBTcl_UtfToUniChar\fR will store the first
 byte of \fIsrc\fR in \fI*chPtr\fR as a Tcl_UniChar between 0x0000 and
 0x00ff and return 1.
