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.

Base library 4.7 (GHC 7.8) or earlier is based on Unicode 6. Base library 4.8 (GHC 7.10) or later is based on Unicode 7. isLower, isSymbol and isPunctuation behave differently.

Character classification

valueisControl :: Char -> Bool

valueisSpace :: Char -> Bool

valueisLower :: Char -> Bool

Source#

This function returns True for 170 and 186 in Unicode 6. But it returns False in Unicode 7.

valueisUpper :: Char -> Bool

valueisAlpha :: Char -> Bool

valueisAlphaNum :: Char -> Bool

valueisPrint :: Char -> Bool

valueisDigit :: Char -> Bool

valueisOctDigit :: Char -> Bool

valueisHexDigit :: Char -> Bool

valueisLetter :: Char -> Bool

valueisMark :: Char -> Bool

valueisNumber :: Char -> Bool

valueisPunctuation :: Char -> Bool

Source#

This function returns False for 167 and 182 in Unicode 6. But it returns True in Unicode 7.

valueisSymbol :: Char -> Bool

Source#

This function returns True for 167 and 182 in Unicode 6. But it returns False in Unicode 7.

valueisSeparator :: Char -> Bool

Subranges

valueisAscii :: Char -> Bool

valueisLatin1 :: Char -> Bool

valueisAsciiUpper :: Char -> Bool

valueisAsciiLower :: Char -> Bool

Case conversion

valuetoUpper :: Char -> Char

Source#

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

valuetoLower :: Char -> Char

valuetoTitle :: Char -> Char

Source#

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