mb_convert_variables -- Convert character code in variable(s)

## Description

``string mb_convert_variables` (string to-encoding, mixed from-encoding, mixed vars)`

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

mb_convert_variables() convert character encoding of variables `vars` in encoding `from-encoding` to encoding `to-encoding`. It returns character encoding before conversion for success, `FALSE` for failure.

mb_convert_variables() join strings in Array or Object to detect encoding, since encoding detection tends to fail for short strings. Therefore, it is impossible to mix encoding in single array or object.

It `from-encoding` is specified by array or comma separated string, it tries to detect encoding from `from-coding`. When `encoding` is omitted, `detect_order` is used.

`vars (3rd and larger)` is reference to variable to be converted. String, Array and Object are accepted. mb_convert_variables() assumes all parameters have the same encoding.

Example 1. mb_convert_variables() example
    /* Convert variables $post1, $post2 to internal encoding */
    $interenc = mb_internal_encoding();
    $inputenc = mb_convert_variables($interenc, "ASCII,UTF-8,SJIS-win", $post1, $post2);
