The String class is used to represent string (textual) data in ActionScript 3.0. ActionScript strings support both ASCII and Unicode characters. The simplest way to create a string is to use a string literal.
To use single quotation marks (') within a string literal defined with single quotation mark (') delimiters, use the backslash escape character (\). Similarly, to use double quotation marks (") within a string literal defined with double quotation marks (") delimiters, use the backslash escape character (\). The following two strings are equivalent:
var str1:String = "That's \"A-OK\"";
var str2:String = 'That\'s "A-OK"';
