JCO Server - function template definition

Question

Hi all,
I'm writing a JCO Server application where I define a function template with three tables each with a number of character fields.
It seems that I need to set the length of each field to the double of the corresponding field of the SAP function.
For example, the field COD_ZONE should be a char(2) (valid value: B1) and then I need to set the char length to 4 otherwise a truncated value is received.
It looks like a double-byte character set is set in SAP environment, but it should not be the case.
Do you have any idea ?
Thanks for helping

Yes,
we have unicode environment.
That means that I can't use following definition ?
fmeta = new JCO.MetaData("FUNC");
fmeta.addInfo("TABLE", JCO.TYPE_TABLE, 2, 0, 0, 0, "HEADER");
repository.addFunctionInterfaceToCache(fmeta);
JCO.MetaData tableMeta = new JCO.MetaData("HEADER");
tableMeta.addInfo("OBJECT_ID", JCO.TYPE_CHAR,  2, -1, 0);
