Do these work correctly with that font? I mean figures 11-2,= =20 > 11-3, and 11-4, as well as tables 11-2 and 11-3.

The Aegyptus font contains= =20 ~10000 glyphs and ligatures, more precisely, ~7500 glyphs and ~2500=20 ligatures. The method chosen in that font is to use ligatures instead of explicit=20 formatting characters, with an "escape" (zero-width non-joiner U+200C) to= =20 display adjacent characters that would have been subject to a ligature=20 separately (one after the other). Both LibreOffice and Harfbuzz=20 understand this, and render Egyptian texts correctly. I just looked at section 11.4 of the Unicode Standard. The first=20 character sequence in figure 11-2 is not a valid quadrat. The second one= =20 are two characters that would normally be placed one above each other, so= =20 to obtain what is displayed in the Unicode Standard it's necessary to=20 separate them with a zero-width non-joiner. --eXI7F4ZSHH--
