I was too hasty! It could be greek afterall. Apparently there where more different styles then i thought.. And many greek explorers visited egypt, anyone of them could have left those markings. I dont know thy the last symnbol has two lines, perhaps they are really two symbols drawn as one, for simplicity?

Or, perhaps it is some Freemasonic twaddle scrawled on the pyramid in the past couple hundred years. :')

It could be a local style (from a non-Egyptian locale) that isn't well attested. Many of the ancient written texts which survive are inscriptions, but most of what was written then (just as now) was on materials which haven't endured. But since it doesn't appear to be even a Greek name, probably it isn't Greek, even if some the characters used appear to be from the Greek alphabet. (':
