I’m slightly confused by this patch. Its description is “update to Unicode
v7.0.0” but the intent also seems to be to update to the ES6 definition of
`Identifier`. However, the current patch only does that partially, as it
doesn’t
support supplementary Unicode symbols. E.g. `eval('var 𐐼')` shouldn’t
throw an
error (`𐐼` is U+1043C DESERET SMALL LETTER DEE).
I'm not particular familiar witb the spec changes in this area. I merely
reran
the script to generate V8's Unicode tables with the data files for Unicode
7.0.0. Thereby I used the same rules to generate the predicates, except
that I
added a predicate Pattern for the properties PATTERN_* to correctly
implement
ID_Start and ID_Continue. I'm not sure how your example is related and
where it
is described in either ES6 or Unicode. Can you give me a tip?
