Description:
------------
When using UTF8 in the database (mySQL 5.5.24-0ubuntu0.12.04.1), fields defined as a certain length aren't returned as the correct length by mysqli_fetch_field_direct. IOW, a char(32) field is shown as actually being 96 chars long because it's 32 * 3 (3 bytes per char instead of one).

The older mysql_field_len correctly reports the length.


Test script:
---------------
// Assuming a single table with a single field 'test' defined as char(32)
// and UTF-8 charset.
$connection = = mysqli_connect ('localhost', 'user', 'password');
$query = "SELECT test FROM test_table LIMIT 1";
$result = mysqli_query ($connection, $query);
$field_info = mysqli_fetch_field_direct ($result, 0);
echo $field_info -> length;


Actual result:
--------------
Returns 96; should be 32.
