Maybe there is something I don't understand, but I also have the
impression that encoding management is strange in Drools.
The "lexer = new DRLLexer( new ANTLRInputStream( is ) );" line indeed
leads to using the default encoding of the machine.
It is the same for the CSV parser (rule templates, Drools 5.1.1):
public void parseFile(final InputStream inStream) {
final BufferedReader reader = new BufferedReader(new
InputStreamReader(inStream));
It means that if I write my rule on a Windows machine (CP1252) and
deploy it on a Linux server (UTF-8), it will not work as expected.
Conditions like...:
Person(firstname == "Béatrice")
... will become things like (CP1252 file "transported" onto a UTF-8
platform and read as UTF-8) :
Person(firstname == "B¤atrice")
I wonder how you deal with that in Guvnor.
Best regards,
Bruno.

Would you please provide a method in 'org.drools.io.ResourceFactory'
like this:
public static Resource newReaderResource(InputStream stream, String
encoding);
then I can use this method to load drl files as a stream while
explicitly specify its ecoding?
And in line: 287 of class 'org.drools.compiler.DrlParser':
lexer = new DRLLexer( new ANTLRInputStream( is ) );
no encoding specified as well. The ANTLRInputStream has constructors
which allows you to specify the encoding, otherwise it would figure
out the encoding according to the environment, which is unpredictable
some times.
I'm using drools 5.3.0, the newest version. Thosse problems exists for
quite a while during previous versions. I'm fainting to see they are
almost there after upgraded to the new version.
