Thank you very much.

Now unicode.js by default (AISB, it is configurable) also replaces 
String.fromCharCode() to support code points beyond U+FFFF (Number arguments 
from 0 to 0x10FFFF), and adds String.prototype.getLength() so that 
"…".getLength() returns the number of Unicode characters in a string, as 
opposed to the built-in "…".length which yields the number of 16-bit code 
units.  More is going to follow.

Thanks to Cezary Tomczyk's test [1] it is also working in IE 10 on Windows 8 
(it was a refactoring bug in object.js).  However, JScript in IE/MSHTML 10 
apparently lacks the ability to define getters and setters for properties of 
native objects as specified in ECMAScript Edition 5.x, so tests using those 
features will always fail.
