Question about PHP-CGI, Unicode Environment, and $_POST

Hello comp.php.windows,

What is the environment variable to define, in order to work fine with unicode
environment, and POST method, in CGI mode?

Regards,
Pierre.

My program launches the php-cgi.exe via a "CreateProcess" having its
"dwCreationFlags" set to "CREATE_UNICODE_ENVIRONMENT". (I have to use a more
recent compiler - previously there was no problem with its "ancient"
ANSI version.)
The $_GET array is still well initialized - which means that the environment set
by my program is still ok, but now the $_POST array seems pretty bad.
Versions <= 5.3 show the issue - versions above 5.3: not checked.
