Neither did I read all these pages nor did I pretend to.

> Neither the wikipedia page for the Didot family, nor for Histoire générale des voyages shows the Angzarr symbol, I've carefully checked on all the scans on these pages.

You have linked these two Wikipedia pages[1][2], implying that they confirm your extraordinary claims of how obvious and well-known this symbol is. I could in fact check within a single day that the symbol does not appear on any of the 15 images linked in these pages.

So unless you can produce evidence for your claim that "that symbol was used as a notation symbol in those star charts and azimutal maps?", it is quite disingenuous to expect anyone to take it seriously. Expecting someone else to read "thousands of pages" to confirm or deny YOUR claim makes it even less worthy of consideration.

If you do have actual, material evidence for your claims, everyone in this thread would very much like to see it.

That's great and all, but the point is that there still isn't a single known (to the community of people trying to find the origins of that symbol, so, safe to say, the vast majority of people in general) appearance of the character in the actual text (i.e. used for its purpose), so if you have an example of a map/book/anything where this character was used, providing the link/scan/photo would be very appreciated.
