<P ALIGN=LEFT>[1] The zint command line program requires Latin-1
characters to be encoded using the UTF-8 system. These are converted
by the front-end into an extended ASCII string. When using the API
this type conversion will need to be done before invoking the library
otherwise the data will become corrupted. An example program
<FONT FACE="Courier, monospace">exttest.c</FONT> is included in the
/<FONT FACE="Courier, monospace">frontend</FONT> folder to show how
extended ASCII can be used to produce the following symbol. Extended
ASCII characters may not display properly in EPS due to the
restrictions of the EPS format.</P>
