You can try using that hack to replace all calls with mysqli if you want but as I stated that is beyond what we support.
I have clearly shown we support UTF as shown here I am using your own user title as an example

Your issue is with using mysqli for
vb and things seem to be stored different so they will be displayed different. If your
vb was using mysql not mysqli it would display right just like my test site
Most programs tell you specifically if they support mysql or mysqli and I know
vb tells you that. No where on your site do we state we support the mysqli extention
I have not looked at whats involved but I beleive you need to change all mysql connect strings etc from examples below
mysql_num_rows
to say
mysqli_num_rows
There might be more to it but you would need to look at that hack you noted and see
