UNICODE Strings in HTML and Javascript

[iwato]

QUESTION:  Is the following an accurate statement?  If not, please clarify how a unicode string literal differs from say, an ASCII string literal.

Quote

A UNICODE character string is an array-object of single character elements each with its own directional indicator.

In Javascript, all strings are internally treated as UTF-16 strings:

http://ecma-international.org/ecma-262/5.1/#sec-8.4

http://speakingjs.com/es5/ch24.html

When a String contains actual textual data, each element is considered to be a single UTF-16 code unit. Whether or not this is the actual storage format of a String, the characters within a String are numbered by their initial code unit element position as though they were represented using UTF-16. All operations on Strings (except as otherwise stated) treat them as sequences of undifferentiated 16-bit unsigned integers; they do not ensure the resulting String is in normalised form, nor do they ensure language-sensitive results.

Have you seen this?  I have just started exploring it.

I'm not familiar with that, I feel like I used something similar to that at one point but that project is only 2 years old so it wouldn't have been that.
