The bug of property list has been fixed.
Thanx a lot!!
There is a last piece which may need some discussion.
The file gnustep/core/gui/Tools/exampleInof.plist contains different
language (encoding).
Sometimes the encoding will conflict with user's local encoding.
In my case, the German umlaut will conflict my NSBIG5StringEncoding
setting
("URL oeffnen" and "Gross schreiben")
and the whole file can't be processed successfully.
Maybe it will be better to convert the file into UTF8,
or use Localizable.strings.
