Do you have access to a project actually using Shift_JIS? Interesting!
I thought they were practically unicorns / non-existent running PHP4,
Can you run
```
var_dump(array(
"biao_hex" => bin2hex("表"),
"zend.multibyte" => ini_get("zend.multibyte"),
"zend.script_encoding" => ini_get("zend.script_encoding"),
"zend.detect_unicode" => ini_get("zend.detect_unicode"),
"mbstring.internal_encoding" => ini_get("mbstring.internal_encoding"),
"mbstring.func_overload" => ini_get("mbstring.func_overload"),
"PHP_VERSION" => PHP_VERSION,
));
```
there? What do you get?
