replacementChar :: Char #
The Unicode character \xFFFD, safely (but unrecoverably) representing
an illegal, invalid, or otherwise unknown character.
ASCII Character Ranges
asciiWhitespace :: [Char] #
Infra:
ASCII whitespace
The ASCII characters defined as whitespace in the HTML standard. Unlike
Haskell's isSpace and anything following that example, does
not include \x11 (VT).
isAsciiAlpha :: Char -> Bool #
Infra:
ASCII alpha
Test whether the character is an alphabetic character in the ASCII range
([A-Za-z]).
isAsciiAlphaNum :: Char -> Bool #
Infra:
ASCII alphanumeric
Test whether the character is either an alphabetic character or a digit in
the ASCII range ([A-Za-z0-9]).
isAsciiWhitespace :: Char -> Bool #
Infra:
ASCII whitespace
Test whether the character fits the spec's definition of asciiWhitespace.
toAsciiLower :: Char -> Char #
Convert an uppercase, alphabetic, ASCII character to its lowercase form.
This has the same semantics within the ASCII range as toLower, but
leaves any non-ASCII characters unchanged.
>>>toAsciiLower 'A''a'
>>>toAsciiLower 'Á''Á'
toAsciiUpper :: Char -> Char #
Convert a lowercase, alphabetic, ASCII character to its uppercase form.
This has the same semantics within the ASCII range as toUpper, but
leaves any non-ASCII characters unchanged.
>>>toAsciiUpper 'a''A'
>>>toAsciiUpper 'á''á'
