Windows-1252, does, however contain a number of undefined codepoints of
its own, and in the conversion tables provided by Microsoft, they are
really undefined. The new Encoding Standard for W3C defines a 1-to-1
mapping for those to the control characters (Windows-1252:0x81 to U+0081,
for instance) [1]. So doing the same for a "true" ISO 8859-1 map is
definitely not unreasonable.
