No, the Unicode grapheme clustering algorithm is not locale or
language sensitive
http://unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries
one final comment: the Unicode algorithm is intended to define default
behavior only:
"This specification defines /default/ mechanisms; more sophisticated
implementations can /and should/ tailor them for particular locales or
environments."
it specifically states that implementations *should* provide
language/locale sensitive behavior;
in actual text processing usage, one needs the language/locale
sensitive behavior in most cases, not a default behavior
Right, and Gecko, WebKit, and other web rendering engines obviously need
to care about this. But they're invariably implemented mostly or wholly
*not* in JS.
It's a bit ambitious for JS to have such facilities.
I agree with Erik that the day may come, but ES6 is being prototyped and
spec'ed and we need to be done in 2012 to have the spec ready for 2013.
We should not overreach.
