Text.XML.Basic.Character
Description
All kinds of representations of a character in XML combined in one type.
Note that an entity can in principle represent a large text,
thus an "XML character" might actually be a text.
However the standard entities consist of one character.
In contrast to our representation,
HaXml uses Unicode substrings instead of Unicode characters,
which is certainly more efficient for common XML texts
that contain mainly Unicode text and only few references.
However our representation is unique,
whereas HaXmls may represent a text as abc,def or abcdef.

toUnicode :: T -> Exceptional String CharSource
If a reference cannot be resolved
then an Exception constructor with an error message is returned.
toUnicodeGen :: Map String Char -> T -> Exceptional String CharSource
toUnicodeOrFormat :: T -> ShowSSource
If a reference cannot be resolved then a reference string is returned.
fromUnicode :: Char -> TSource
fromCharRef :: Int -> TSource
fromEntityRef :: String -> TSource
maybeUnicode :: T -> Maybe CharSource
maybeCharRef :: T -> Maybe IntSource
maybeEntityRef :: T -> Maybe StringSource
isEntityRef :: T -> BoolSource
asciiFromUnicode :: Char -> TSource
Convert unicode character to XML Char. If there is a entity reference, use this. If it is ASCII, represent it as Char. Otherwise use a character reference.
reduceRefGen :: Map String Char -> T -> TSource
try to convert a References to equivalent Unicode characters
validCharRef :: Int -> BoolSource
