This abstract provides consistent cross-target unicode support for characters of any width.
Due to differing internal representations of strings across targets, only the basic
multilingual plane (BMP) is supported consistently by String class.
This abstract provides API to consistently handle all characters even beyond BMP.

Static methods
staticcharAt(this:String, index:Int):String
Available on js, jvm, cpp, flash, hl
Returns the character at position index of this String.
If index is negative or exceeds this.length, the empty String ""
is returned.
staticcharCodeAt(this:String, index:Int):Null<Int>
Available on js, jvm, cpp, flash, hl
Returns the character code at position index of this String.
If index is negative or exceeds this.length, null is returned.
staticindexOf(this:String, str:String, ?startIndex:Int):Int
Available on js, jvm, cpp, flash, hl
See also:
String.indexOf
staticinlineiterator(this:String):StringIteratorUnicode
Available on js, jvm, cpp, flash, php, macro, hl, lua, python
Returns an iterator of the unicode code points.
staticinlinekeyValueIterator(this:String):StringKeyValueIteratorUnicode
Available on js, jvm, cpp, flash, php, macro, hl, lua, python
Returns an iterator of the code point indices and unicode code points.
staticlastIndexOf(this:String, str:String, ?startIndex:Int):Int
Available on js, jvm, cpp, flash, hl
Returns the position of the rightmost occurrence of str within this
String.
If startIndex is given, the search is performed within the substring
of this String from 0 to startIndex + str.length. Otherwise the search
is performed within this String. In either case, the returned position
is relative to the beginning of this String.
If str cannot be found, -1 is returned.
staticsubstr(this:String, pos:Int, ?len:Int):String
Available on js, jvm, cpp, flash, hl
Returns len characters of this String, starting at position pos.
If len is omitted, all characters from position pos to the end of
this String are included.
If pos is negative, its value is calculated from the end of this
String by this.length + pos. If this yields a negative value, 0 is
used instead.
If the calculated position + len exceeds this.length, the characters
from that position to the end of this String are returned.
If len is negative, the result is unspecified.
staticsubstring(this:String, startIndex:Int, ?endIndex:Int):String
Available on js, jvm, cpp, flash, hl
Returns the part of this String from startIndex to but not including endIndex.
If startIndex or endIndex are negative, 0 is used instead.
If startIndex exceeds endIndex, they are swapped.
If the (possibly swapped) endIndex is omitted or exceeds
this.length, this.length is used instead.
If the (possibly swapped) startIndex exceeds this.length, the empty
String "" is returned.
