It's interesting to see that Google translate will not stay within the Greek alphabet in a single word and will try to insert the closest matching letter from another alphabet. In your example, it matched "ΡΕΓΓΟYKOY" to "ΡΕΓΓΟVKOV", even though there is no letter V in the Greek alphabet.
Is that what that says? That road sign tripped me up so much, since it definitely looks like a "V" to me (the uppercase ypsilon looks nothing like a V).
