 The problem is that the result of the expansion should depend
 on the html doc's charset/encoding.  For example, in euc-jp, ©
 should be {0x8f, 0xa2, 0xed}, but tidy always think it as 0xa9.
 And many browsers interpret © as a raw character in the html
 doc's charset (euc-jp, in this case).   , ©, &#183, and
 other >159 characters in euc-jp are different from iso-8859-*.

 While according to the XML specification it is unambiguous (&#xxx;
 is always interpreted as a Unicode character), I think it is better
 that entity is preserved as it is at the present moment.  Tidy does
 not know the relationship between euc-jp and Unicode, so a lot of
 Japanese docs will be broken without -preserve.
