SRM Catalog Download

Question

Hi all
I need to download the full SRM Catalog structure together with all details from SRM to logcal XML file.
I've checked all around here on SDN but have not comed up with a clear solution...
One of these were : http://forums.sdn.sap.com/thread.jspa?threadID=1217084
My concern is more or less UNICODE..
So far I have tested this
- I have a deep structure with all the data about the Catalog structure <t_dyntable>
- then I try to convert this contents into UTF-8. By doing this I will get some of the special characters to show up as they should ( it think one of those were .amp that were successfully translated to &)
- Then CALL TRANSFORMATION were done to get the XML-file
Below you can see some different way's I have tried... Trying to use XSTRING.... and download via type BIN for GUI_DOWNLOAD. My starting point was with UTF-16, but with that I could not read the XML file at all - With UTF-8 I can read it but still as soon as some kind of special sign shows up the XML-editor complains about - Not allowed letter. Please help
Best regards

Hi again
With coding above the download xml-file will contain
&amp :  is interpreted as & in the xml-editor = OK
BUT the file contains other special signs that do not work:
± :  is not interpreted ok. XML-editor will stop analyzing the file = NOT OK
Do you know if I could use another way of codepage or something to also handle these special signs.
Best reg
