Bug #26280 MYSQL Problem with Greek Characters

Description:
I have a problem with the greek characters stored in my database.....

I have my 'MY.ini' file set to 

default-character-set=utf8
default-collation=utf8_bin

I have realised that MYSQL regard the greek letter 'Δ' (delta) and the greek letter 'Ε' (epsilon) as the same!!!!

In one of my tables called "Documents", I have a field called "Description"
I have two records whose "description" are "ΔΟΧ" (Delta,omikron,chi) and "ΕΟΧ" (Epsilon,omikron,chi).

When I execute the query:
    select *
    From Documents
    where "description" LIKE 'ΔΟΧ'

The result is I get both records (ΔΟΧ and ΕΟΧ)

I've been on numerous forums and all recommend to add the word 'BINARY' in the "where" clause. When this is added I receive no results even though the character case is identical!! 

The same problem may occur with other greek characters but I have yet to try

Thankyou

How to repeat:
1) Create a table with one field name lets say "Description"
2) use UTF8 as character set and utf8_bin as the collation
3) Add two records naming them 'ΔΟΧ' (delta,omikron,chi) and                   'ΕΟΧ' (Epsilon,omikron,chi)
4) execute the following SQL statement:
   select *
    From <tablename>
    where <fieldname> LIKE 'ΔΟΧ'
5) Wrongly the result will include the record 'ΕΟΧ'

Thank you for the report.

Please indicate accurate minor version of the server you use.

The MYSQL version I am using is 5.0 although I have tried the same scenario using MYSQL 5.2 beta and the problem still persists

Thanks
