http://www.mozilla.org/js/tests/library.html for information about these tests, like how to run them and stuff. According to fur, these tests should not get checked out when you check out Mozilla -- you'd have to specifically check out mozilla/js/tests to get all these files.

ECMA Section: 15.5.4.5 String.prototype.charCodeAt(pos)
|
|
Description: Returns a number (a nonnegative integer less than 2^16)
|
|
representing the Unicode encoding of the character at
|
|
position pos in this string. If there is no character
|
|
at that position, the number is NaN.
|
|
|
|
When the charCodeAt method is called with one argument
|
|
pos, the following steps are taken:
|
|
1. Call ToString, giving it the theis value as its
|
|
argument
|
|
2. Call ToInteger(pos)
|
|
3. Compute the number of characters in result(1).
|
|
4. If Result(2) is less than 0 or is not less than
|
|
Result(3), return NaN.
|
|
5. Return a value of Number type, of positive sign, whose
|
|
magnitude is the Unicode encoding of one character
|
|
from result 1, namely the characer at position Result
|
|
(2), where the first character in Result(1) is
|
|
considered to be at position 0.
|
|
|
|
Note that the charCodeAt funciton is intentionally
|
|
generic; it does not require that its this value be a
|
|
String object. Therefore it can be transferred to other
|
|
kinds of objects for use as a method.
