So now there's going to be a PHP-ICU extension for PHP 5 and PHP 6, and PHP 6 will have ICU built-in to such an extent that it's backwards compatible with PHP 5?
Both extensions would be (are being) written in such a way that code that worked on PHP 5 would work on PHP 6, with regard to the extension. Of course, particular code still could fail for some other reason, not related to the ICU extension. I.e. if you call collator_sort($foo, $bar), collator_sort being ICU extension function, it would mean the same in PHP 5 and PHP 6.
And what in the world would you do with PHP-ICU extension in PHP 6? I mean, unless you've type-casted a string to binary or whatever, it's already ICU, no?...
I think you are confusing UTF-16 and ICU. ICU is a huge library of Unicode text functions, which so far weren't supported in PHP except for some collation support. There's a lot of functions to add there. UTF-16 is just a way to represent text in bits (and ICU uses it, and so does PHP 6). The extension would expose a part of ICU functionality to PHP users - such as collators, formatters, resources, etc.
