vB4 Database Convert to UTF8

Hello guyz,
new member in vBseo and i have just ordered my license!

I have a vB4 forum in Greek language and cause of some issues lately with unicode support i would like to convert my database to utf8!
I thought that converting prior to vbseo installation would be the best thing to do!

I have seen that there is a product in vbulletin.org which has worked for some in vB3.X series, so is also ok to use this with vB4?
Do you have any other options which you may have used to do this?

Any help would be appreciated

Database tools script to convert your database or if you didn't have it you can convert your database with this Mod vCharset Converter - enjoy the AJAX & UTF-8 - vBulletin.org Forum WORKS WITH vBulletin 3.8

So is this gonna work with my vb4 database or i am gonna cause more problems?
Is it tested in other words with vb4?

(Thanx for the link)

It probably will not work on a vb4.

So is there any suggestion for what i want to do?

You need to contact mod_author and ask more info from them. Unfortunately we can't say anything at all.
