Java Mapscript - querybyattribut SOLVED

Tue Apr 18 09:11:39 EDT 2006

Please add the list to cc (reply to all) so that everybody can benefit
fro this ongoing discussion.

That said I think you need to check some things (I haven't a recipe
ready yet so we'll go by trial and error):

1)that you environment is correctly setup with regard to
internationalization (ie LANG and LC_* variables)

2) after that try to dump the content of the dbf file with dbfdump and
see that content is correctly displayed (you might want to use xterm
which does a better job that gnome-terminal for instance in displaying
non-ascii characters)

3) open the Java source file with an editor like gedit (from GNOME)
which will tell you the encoding of the java source and optionally
recode it to the same encoding set by the LANG variable (use the
recode command under linux).

Best regards,
Umberto
