Re: unexpected BOM in XML file

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Hiya Charles,

I had a couple of comments.

1) A BOM is a unicode thing.  CCSID 819 isn't Unicode, and that's why it 
causes problems to have a BOM there.

2) No, you cannot expect Java or PASE to automatically set the CCSID to 
1208 for you.  Remember, Java is a cross-platform language, and CCSIDs 
are pretty much IBM-specific, I've never seen them anywhere else.  
(They're a great feature, though -- I wish all platforms had them... but 
they don't.)    Probably Java doesn't do anything with the CCSID at all, 
and PASE sets it to whatever PASE uses for a default, which is 819 in 
the US and most western counties.  It has no idea what the CCSID is 
supposed to be, its just a default.

3) The results you're seeing don't seem weird to me.  With CCSID 1208 
(UTF-8) the system expects the BOM and ignores it -- it's still there, 
of course, so you see it in the hex dump -- but it realizes its not part 
of the data, so won't try to display it to the user or parse it in the 
XML document.   This seems normal. Since BOMs don't exist in CCSID 819 
(iso-8859-1) it thinks they are special characters or control characters 
or something like that, and since that type of character isn't valid in 
that spot of an XML document you get the error.  Seems like 
correct/normal behavior to me.
