Invalid byte & SAXParseException

[Carl Smith]

I get regularly get order data provided from a third party in XML and until recently I have not had any issues, but now I am getting import error messages - but only intermittenty.

The error messages read either;

XML parsing error:

Invalid byte ‘a’ at position 2 of a 3-byte sequence

Line Number: 1

Column Number: 22

or;

Filemaker Error Message;

SAXParseException: invalid byte ‘n’ at position 2 of a 3-byte sequence (Occurred in entity File Location at line 1230, column 23.)

I thought, perhaps, that having recently upgraded to FP11 it might have something to do with that, but a colleague still using FP10 has experienced the same thing when running the import on his machine.

Does anyone know why this may occur and what may cause it - especially allowing for the fact that it appears to be an intermittent problem?
