fromCode

fromCode :: KeyCode -> Char

isLower

isLower :: Char -> Bool

True for lower case ASCII letters.

isDigit

isDigit :: Char -> Bool

isOctDigit

isOctDigit :: Char -> Bool

True for ASCII octal digits [0-7].

isHexDigit

isHexDigit :: Char -> Bool

True for ASCII hexadecimal digits [0-9a-fA-F].

toLocaleUpper

toLocaleUpper :: Char -> Char

Convert to upper case, according to any locale-specific case mappings.

toLocaleLower

toLocaleLower :: Char -> Char
