Char Query Operations

FluentQuery supports the following operations when querying chars from a container (eg, a String, or a TList<char>):

Operation	Bound	Unbound	Terminating	Description
First	Yes	Yes		Enumerate the first item, ignoring the remainder.
From		Yes		From allows you to specify the source of the data you are querying. It is also From which transforms an Unbound Query into a Bound Query.
IsControl	Yes	Yes		Enumerates items that are Unicode control characters
IsDigit	Yes	Yes		Enumerates items that are Unicode digits
IsHighSurrogate	Yes	Yes		Enumerates items that are Unicode high surrogates
IsInArray	Yes	Yes		Enumerates only items that are also found in a supplied Array of Char
IsLetter	Yes	Yes		Enumerates items that are Unicode letters
IsLetterOrDigit	Yes	Yes		Enumerates items that are Unicode digits or letters
IsLower	Yes	Yes		Enumerates items that are lower case
IsLowSurrogate	Yes	Yes		Enumerates items that are Unicode low surrogates
IsNumber	Yes	Yes		Enumerates items that are Unicode numbers
IsPunctuation	Yes	Yes		Enumerates items that are Unicode punctuation characters
IsSeparator	Yes	Yes		Enumerates items that are Unicode separator characters
IsSurrogate	Yes	Yes		Enumerates items that are Unicode surrogates
IsSymbol	Yes	Yes		Enumerates items that are Unicode symbols
IsUpper	Yes	Yes		Enumerates items that are upper case
IsWhitespace	Yes	Yes		Enumerates items that are Unicode whitespace characters
Matches	Yes	Yes		Enumerates items that match the supplied Char. Can be either case-sensitive or insensitive, but is insensitive by default.
Predicate		Yes	Yes	Returns a TPredicate<Char> encapsulating the Unbound Query logic.
Skip	Yes	Yes		Skip will bypass the specified number of items from the start of the enumeration, after which it will enumerate the remaining items as normal.
SkipWhile	Yes	Yes		SkipWhile will bypass items at the start of the enumeration while the supplied Predicate evaluates True. Once the Predicate evaluates false, all remaining items will be enumerated as normal.
Take	Yes	Yes		Take will enumerate up to the specified number of items, then ignore the remainder.
TakeWhile	Yes	Yes		TakeWhile will continue enumerating items while the supplied Predicate evaluates True, after which it will ignore the remaining items.
ToAString	Yes		Yes	Returns a String containing the Chars that match the query
Where	Yes	Yes		Filter the items enumerated to only those that evaluate true when passed into the supplied Predicate
