dread questionmark disease

n. The result of saving HTML from Microsoft Word or some other program that
uses the nonstandard Microsoft variant of Latin-1; the symptom is that
various of those nonstandard characters in positions 128-160 show up as
questionmarks. The usual culprit is the misnamed smart quotes feature in
Microsoft Word. For more details (and a program called demoroniser that
cleans up the mess) see http://www.fourmilab.ch/webtools/demoroniser/.
