Examples of Greek capital ου ligature wanted

Andreas Stötzner

It occurs in lettering, shop signs and on packaging. I wonder if someone has more examples of the Greek capital ου glyph at hand. Printed specimen would be especially interesting.

The Παπαδοπουλου brand is perhaps the best known today …

In terms of text representation and font implementations, I would assume the text representation should be as the sequence "ου" and that letterforms be formed as ligature substitution in the font. Is there any reason to consider otherwise? 

Andreas Stötzner

As for merely a typographic representation in a language text, it seems suitable to rely on the ligature solution you suggest. But, what if the character (glyph?) appears in another context, e.g. in a math manuscript where it is obviously used as an alphanumeric symbol in formulæ?

In this manuscript from Leibniz it is conspicious that the author deliberately attaches capital-style serifs to the ου shape which would otherwise would have passed as a minuscule (which was rather common in Greek writing then). The source is not published yet and the correct interpretation of that sign has not achieved a final approval by editors, but it seems likely that the reading “capital ου” proves true. So, for a future facsimile edition of that text, the question arises: how to encode these passages properly?

In a math context, can one definitively say that this is ‘Greek’, in the sense of something like a Unicode character-level script property?

Might this be encoded using the existing Latin character
Ȣ   U+0222   LATIN CAPITAL LETTER OU

For that author, if it is a letter, it could only be either Latin, Greek or Hebrew. But, since the “LATIN CAPITAL LETTER OU” is a rather modern invention (the idea of it being borrowed from either the familiar Greek or Cyrillic letters), U+0222 would certainly be an inappropriate choice for a source from around the year 1700.

Not sure if you want native Greek examples only, but here is the ligature in my Quinoa:
