Hi all,

I've started cautiously poking PHP 6 so I can keep an eye on how the Unicode
support is going and see what kind of work we'll eventually need to do to port
MediaWiki for it...

One thing I noticed right off is that this test doesn't do what you'd expect if
you didn't copy in one of the sample php.ini files:

if(ini_get("unicode_semantics")) { /* bla bla */ }

The default value for unicode_semantics is the literal string "off", which
evaluates to true although the setting really is off.

Attached is a one-line patch which sets it to "0" and uses the macro
STD_ZEND_INI_BOOLEAN, to match with other config settings I saw in there. This
keeps it off by default but makes the ini_get evaluate to the expected false in
a boolean test.

Hello Brion,

  i applied your fix which was correct. I however also added a function to
check for unicode mode "bool unicode_enabled()" which returns true if
unicode_semantics is set true.

best regards

I don't think it's right to call it unicode_enabled(). Unicode is 
always accessible, it's just that certain language semantics don't use 
it when unicode_semantics is off. So I'd call the function 
unicode_semantics() or unicode_default().

Hello Andrei,

  changed to unicode_semantics() now.

thanks for the hint.
