No character has an ASCII value greater than 127: ASCII is a 7-bit
encoding. Of course, it's possible to use characters beyond ASCII,
since the Document Character Set for XML is Unicode.

Perhaps your XML declaration doesn't agree with the actual encoding
of the document (you don't say what either of these are for your
document). See Sections 2.8 and 4.3.3, and Appendix F.

Of course - the parser is unlikely to be able to tell the difference
between the various parts of ISO 8859, for instance.
Steffen> How can I communicate this character set to an XML parser?
In the encoding declaration, <?xml encoding="utf-8"?> (or whatever).
You may prefer to write the problematic characters as entities or
character references, if they are rare in your source. This may
allow you to write your documents in a smaller character set. (As an
example, I find it easiest to author in ISO-8859-1, but I need to
define entities for the Welsh characters, which lie in the Latin-2
