;; The Egyptian Hieroglyph Format Controls were introduced in Unicode
;; Standard v12.0. Apparently, they are not yet well supported in
;; existing fonts, as of late 2020. But there's no reason for us not

;; Hieroglyphs in "quadrats", as directed by the format controls,
;; which specify how the hieroglyphs should be joined horizontally and
