The short answer is that it's a mistake to read my comment as saying 7 segments per se in the usual figure-8 shape is universal to how brains comprehend writing. It's not. You can dig up counter examples all day because that wasn't my point.
My point was that for a given language, the writing system tends to evolve to the point where each glyph contains just enough distinguishing features to not confuse it with any other glyph. There is also selective pressure to reuse the same segments but in different combinations, rather than try and come up with wholly different lines for each glyph which can only be learned by rote memorization. The end result of these pressures is that any language will evolve towards its own version of a 7 segment display. Call it a k-segment display, where k is only slightly higher than log_2(the size of the alphabet). I don't know what the k segment display looks like for Cyrillic or Greek or whichever other alphabet you pulled the other glyphs from, but I'm sure one could be found.
It definitely exists for Korean, as the Korean alphabet was designed in the 19th century and the sub-letters are intentional. I mention this because one of your chosen examples is a Korean letter.
