String.prototype.reverse(), as proposed, corrupts supplementary characters.
Clause 6 of Ecma-262 redefines the word "character" as "a 16-bit unsigned
value used to represent a single 16-bit unit of text", that is, a UTF-16
code unit. In contrast, the phrase "Unicode character" is used for Unicode
code points. For reverse(), this means that the proposed spec will reverse
the sequence of the two UTF-16 code units representing a supplementary
character, resulting in corruption. If this function is really needed (is
it? for what?), it should preserve the order of surrogate pairs, as does
java.lang.StringBuilder.reverse:
