> My question is why does V8 (or anything else) still use UCS-2? Because the ES spec defines a string as a sequence of UTF-16 code units (aka UCS-2-with-visible-surrogates), because as many others (e.g. Java) the language's strings were created during/inherited from Unicode 1.0 which fit in 16 bits (UTF-16 is a retrofitting of Unicode 1.0 fixed-width to accomodate the full range of later unicode version by adding surrogate pairs) |
