Hello,
I think that Rowan is right: PHP users need to manipulate grapheme clusters
first (and code points in some rare situations). The fact that most of us
live in a world were NFC composes all our characters only hides this
reality.
A typical use case is a template engine: nearly all string man

Rowan,
What is confusing me is that i think you're seeing it as a major
implementation defect. To avoid arguable implementations, i've made
short example in Java:
System.out.println(new StringBuffer("noël").reverse().toString());
It does produce string

Back to combining characters, i dig the idea of introducing graphemes,

If you went length in characters, you probably need to implement your own

I disagree, Unicode has very well-defined algorithms for these things,

Rowan,
As I've mentioned before, a lot of the time what people actually want to
deal with is "grapheme clusters" - the kind of thing that you'd think of
as a character if you were writing by hand. Most people, if asked the
length of the string "noël", wo

Unicode string support.
I know that was probably deliberately flippant, but I think there is a
genuine question to be asked here. A lot of people talk about "Unicode

It would add a UString class to PHP for Unicode strings. This would make

Attached is the patch which adds Unicode support to *printf() functions stack.
We (Andrei and me) made several assumptions that are worth mentioning:
sprintf() and vsprintf():
