<br><font size=2 face="sans-serif">Hi</font>
<br>
<br><font size=2 face="sans-serif">The C-Wrapper "mapscript_wrap.c"
converts Java-Strings to</font>
<br><font size=2 face="sans-serif">"char*" with the JNI-Function
"GetStringUTFChars".</font>
<br><font size=2 face="sans-serif">This UTF-8-byte-sequence is passed to
the mapserver-kernel.</font>
<br><font size=2 face="sans-serif">But mapserver-kernel expects an one-byte-encoding.
(ISO-8859-1 or CP437 (!?))</font>
<br>
<br><font size=2 face="sans-serif">I wrote a JNI-sample-program to illustrate.
</font>
<br><font size=2 face="sans-serif">The sample-program converts to UTF-8,
ISO-8859-1 and CP437.</font>
<br><font size=2 face="sans-serif">On my Windows-Command-Prompt the CP437-result
was correct.</font>
<br>
<br><font size=2 face="sans-serif">I think mapscript_wrap.c has to do more
than UTF-8-Conversion.</font>
