<p class=MsoNormal style='text-indent:6.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>My original plan was to generate a
private GeoTiff key tag and store the Unicode string as the value for that tag.
As GTIFKeySet() only supports types SHORT, DOUBLE, and ASCII, I planned
to treat the Unicode string as type SHORT with a length equivalent to the
actual string length. Looking at the source code for GTIFKeySet(), I find
that parameter “count” must equal 1 value for types SHORT and
DOUBLE. I can not use type ASCII and pass in a proper string length for
the “count” parameter because GTIFKeySet() ignores the “count”
parameter and does a strlen() instead. Since some Unicode characters have
a leading 0 byte, that method would not work for all possible characters in a
Unicode string.<o:p></o:p></span></font></p>
