Subject: Re: [PHP-DEV] Deprecate declare(encoding='...') + zend.multibyte +
 zend.script_encoding + zend.detect_unicode ?
From: divinity76@gmail.com (Hans Henrik Bergan)

actually scratch that, run
```
var_dump(array(
    "biao_hex" =3D> bin2hex("=E8=A1=A8"),
    "zend.multibyte" =3D> ini_get("zend.multibyte"),
    "zend.script_encoding" =3D> ini_get("zend.script_encoding"),
    "zend.detect_unicode" =3D> ini_get("zend.detect_unicode"),
    "mbstring.internal_encoding" =3D> ini_get("mbstring.internal_encoding")=
,
    "mbstring.func_overload" =3D> ini_get("mbstring.func_overload"),
    "PHP_VERSION" =3D> PHP_VERSION,
    "raw_script_bytes" =3D> bin2hex(file_get_contents(__FILE__)),
));
```
what do you get?
