libtext-unidecode-perl 1.23-1 (amd64 binary) in ubuntu xenial

 It often happens that you have non-Roman text data in Unicode, but
 you can't display it -- usually because you're trying to
 show it to a user via an application that doesn't support Unicode,
 or because the fonts you need aren't accessible. You could
 represent the Unicode characters as "???????" or
 "\15BA\15A0\1610...", but that's nearly useless to the user who
 actually wants to read what the text says.
 .
 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.)
