ISO 8859-1
ISO 8859-1, aka Latin-1, is the most widely used encoding of the ISO 8859 family for English-language text. Windows 1252 encoding includes all the printing characters of ISO 8859-1 and includes additional printing characters by replacing some control characters of the C1 (128-159) range (and often web developers, e-mail software, and other people and programs that generate or transmit text, mistakenly identify Windows-1252-encoded documents as ISO-8859-1 in headers and parameters).
ISO 8859-1 was updated to ISO 8859-15, called Latin-9, replacing some of the less used characters and adding the Euro (€) sign. However, those who have decided to update from Latin-1 have generally gone straight to Unicode, so Latin-9 has not become a widespread replacement. ISO 8859-9 or Latin-5, designed for use with Turkish scripts, also differs from Latin-1 in only a few code points.
The Latin-1, Latin-9, and Windows 1252 encodings all incorporate the ASCII characters in the first 128 code points (0-127), including the C0 controls.
