strange problem - different encoding linux windows in xslt

[matatu]

Hi to all,

my program java applies some trasforms xslt to a file xml using the
attribute encoding = "ISO-8859-1": it work fine under windows xp, but if
I run the program on a pc with redhat ES the file output it contains '?'
to the place of the accented characters...

I apply the trasforms like following:

tFactory = TransformerFactory.newInstance();
transformer = tFactory.newTransformer(new
javax.xml.transform.stream.StreamSource(arrayXslt[0]));
transformer.transform(new
javax.xml.transform.stream.StreamSource(finput),new
javax.xml.transform.stream.StreamResult (new
FileOutputStream(arrayOut[0])));

I hope to have been clear...

thank you for any suggestion
Mark
