Obviously you didn't read the discussion thread in the php bug report :)

In Greek, there aren't only two "a" characters, there are four:

"Α" == "ά" == "α" == "Ά"
"Η" == "ή" == "η" == "Ή"
etc...

Thus, the default method, at least as is in PHP PCRE, doesn't support accented characters.

As a result, the string "ΚΙΝΗΤΗΡΑ" does not match "κινητήρα", which is wrong.
