#36 can not insert greek in database

[Milo Peer]

I have:
mySQL 5.0.16
database name 'inventory' DEFAULT CHARACTER SET greek
php 5.1.1 with PEAR:DB
Win XP Pro SP2
IIS 5.1

installed anyInventory 2.0 by the book (README.txt)
I am trying to add ANYTHING in the db in Greek and
error occurs.

example of error:
>> created a category 'PC'
>> Adding item 'Υπολογιστής' (greek word for Computer)
error occurs

- DB Error: unknown error

- INSERT INTO `anyInventory_items`
(`id`,`item_category`,`name`) VALUES ('1', '1',
'Υπολογιστής')

I think it needs to define somewhere and somehow the
character set of inserting data...

I use iso-8859-7

Any help?
