UTF-16 SS.JS
According to the ECMAScript specification, section 6.1.4. (The String Type), “The String type is the set of all ordered sequences of zero or more 16-bit unsigned integer values (‘elements’) up to a maximum length of 253 – 1 elements. The String type is generally used to represent textual data in a running ECMAScript program, in which case each element in the String is treated as a UTF-16 code unit value.” UTF-16 SS.JS is an open source module that provides additional UTF-16 functionality to JavaScript.
This module implements something that doesn't change over time and is therefore not subject to continual development, but to permanent term support (PTS). This module only implements a standard and is therefore not subject to continual development, but to permanent term support (PTS). The codes in this module are taken from SS.JS and therefore should only be used when SS.JS is not used.
