Data.Char8

Char8 library to be used with Data.ByteString.Char8. All function assumes that only 8bit part of Char is used and it is encoded in Latin-1 (ISO-8859-1). All utility functions are supposed to work as if those of Char. Exceptions are described in the function documentations.

Character classification

isControl :: Char -> Bool

isSpace :: Char -> Bool

isLower :: Char -> Bool

isUpper :: Char -> Bool

isAlpha :: Char -> Bool

isAlphaNum :: Char -> Bool

isPrint :: Char -> Bool

isDigit :: Char -> Bool

isOctDigit :: Char -> Bool

isHexDigit :: Char -> Bool

isAsciiLower :: Char -> Bool

Case conversion

toUpper :: Char -> Char

Micro sign/mu (0xb5) and small letter Y with diaeresis (0xff) remain the same.

toLower :: Char -> Char

toTitle :: Char -> Char

Micro sign/mu (0xb5) and small letter Y with diaeresis (0xff) remain the same.
