What Text::Unidecode provides is a function, unidecode(...) that takes
Unicode data and tries to represent it in US-ASCII characters (i.e., the
universally displayable characters between 0x00 and 0x7F). The representation
is almost always an attempt at transliteration-- i.e., conveying, in Roman
letters, the pronunciation expressed by the text in some other writing system.
(See the example in the synopsis.)
