Storage of UTF-8 char in MySQL

[Ryan Chan]

According to this document:
http://dev.mysql.com/doc/refman/5.0/en/charset-unicode.html

It said MySQL support UTF-8 using one to three bytes per character.

But I have created a test table:

-- create table test ( c char(5) ) default charset =utf8;

From the table status, the data length is alway a multiple of 16.

So how does it support 3 byte UTF-8 in practice?


Thanks
