There are two possible explanations. Either the file contains an instance of the Unicode codepoint 0x0, correctly encoded. XML does not allow this character.

Alternatively, the parser thought it saw an instance of 0x0 because it was decoding the physical bytes of the file incorrectly: that is, the encoding assumed by the XML parser is not the actual encoding of the file.

When you're dealing with this kind of question you need to be very careful about phrases like "I can read the whole file" and "it looks fine". You can't actually see the bits on the disk, you can only use some kind of viewing tool to interpret them for you, and you need to be clear about what tool you were using and how it was configured.
