As at least some of you would already be aware, there's a long-standing issue with using PHP in a Turkish or Azeri locale, namely that case-insensitive lookups within the Zend engine (method names, for example) fail on lookups involving upper-case I characters, since lower-case I in those languages is ı instead of i (note the lack of a dot).
The long term plan for this, per bug #35050 and any number of duplicates, was to deal with it in PHP 6. Since PHP 6 isn't going to happen in its original form, I think we're going to need to revisit how we want to deal with this. There's a patch linked in the bug from Tomas Kuliavas and Marcus that fixes the problem by simply redefining zend_tolower() to a simple locale-insensitive ASCII tolower() function, which does fix the Turkish and Azeri locales. The potential breakage from this is that single-byte locales will no longer get case-insensitive lookups of non-ASCII characters: for example, somebody using fr_FR.ISO-8859-1 as a locale could no longer call a method É() as é(). Since it doesn't break anything when using multi-byte locales (which have never had case-insensitive lookups anyway since the Zend Engine uses the single-byte tolower() internally), my inclination would be to apply the patch on trunk and document it as a BC issue. I've uploaded an updated version of Tomas's patch that applies cleanly to trunk to http://www.adamharvey.name/patches/35050/zend_operators.c.diff and a phpt file to test the fix to http://www.adamharvey.name/patches/35050/bug35050.phpt. It's likely that the test would require massaging before being committed to work on Windows, but since I don't have a Windows development box readily available and don't know a thing about how Windows implements locale support, this would require help from someone familiar with the platform. So: thoughts; concerns; alternate approaches? It would be nice to have this sorted for PHP.next.
