Description

This module treats Bytes data as holding text encoded in ISO-8859-1. This encoding can only encode codepoints strictly below U+0100, but this allows each codepoint to be placed directly into a single byte. This range consists of Unicode Basic Latin, Latin-1 Supplement and C0+C1 Controls, which includes ASCII.

Strictly, ISO-8859-1 is not to be confused with ISO/IEC 8859-1 (which was the default encoding for webpages before HTML5). ISO/IEC 8859-1 lacks encodings for the C0 and C1 control characters.

With HTML5, the default encoding of webpages was changed to Windows-1252, which is _not_ compatible with ISO-8859-1. Windows-1252 uses the C1 Control range (U+0080 -- U+009F) mostly to encode a variety of printable characters. For this encoding, see Windows1252.

Documentation

toString :: Bytes -> String Source #

Interpret a byte sequence as text encoded by ISO-8859-1.

fromString :: String -> Bytes Source #

Convert a String consisting of only characters representable by ISO-8859-1. These are encoded with ISO-8859-1. Any character with a codepoint above U+00FF is replaced by an unspecified byte.

decodeDecWord :: Bytes -> Maybe Word Source #

Decode machine-sized word from decimal representation. Returns Nothing on overflow. Allows any number of leading zeros. Trailing non-digit bytes cause Nothing to be returned.
