LPX-00200: could not convert from encoding UTF-8 to UCS2 during

Question

When doing an query with SQL/XML on a database with the following characterics
NLS_LANGUAGE -- AMERICAN
NLS_CHARACTERSET - UTF8
NLS_NCHAR_CHARACTERSET - AL16UTF16
Database version is 9.2.0.5.0
I get the following error on a text with special characters
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00200: could not convert from encoding UTF-8 to UCS2
I used the tip from another developer to use the convert function :
XMLForest(convert(train.programma, 'UTF8', 'WE8ISO8859P1') AS "programma"
Now at least I don't get the error but in the resulting all special characters (and there are a lot of them!) are garbled
So for example (hope this comes across during the post)
original : coördinatoren
in xml : coördinatoren
Any suggestions here? I'm not really allowed to change any database-parameters or doing an upgrade
Maybe using something else in the convert function?

Here's the complete query (with the convertfunction in it). Hope this helps
