Ruby's Greek Thread

Perhaps you should consider that such signs were already used in old books.
See, for example, the NSA report.
The best thing, however, will be for you to read through the various comments here at Ninja.

Do you mean that those signs were known when the ms was written? Even if it is the case it doesnt mean than they were used with the same meaning, they could be used to decive the readers.
I have read the various comments here at Ninja, any idea can serve as inspiration for another idea.
