Right, the HTTP header does specify utf-8. I think it would be a good
idea to include a <meta> element in the document too. Hv3 assumes
utf-8, but major browsers seem to assume 8859 when loading a file://

One reason I got so confused is that t040302-c61-ex-len-00-b-a.htm
appears to pass in current versions of major browsers on linux if
loaded with 8859 encoding. This is because they get both the "test"
and "control" blocks wrong in this case - the test block is wrong because
the metrics of the Ahem font are not being interpreted correctly and
the control block is wrong because the wrong glyph is selected due to
the 8859 encoding. Unfortunately, the two "wrong" renderings are identical,
so to the casual observer the test appears to pass!
