I will > then try to find time to test this idea. 1. The most obvious is prettify-symbols-mode in Emacs sources Say, (setq-local prettify-symbols-alist '(("!" . ?=C2=AC)) M-x prettify-symbols-mode 2. https://github.com/integral-dw/org-superstar-mode You can use tests/*.org example files Also, https://github.com/jdtsmith/shakespeare.org has a giant example Org file. And https://github.com/casouri/valign/blob/master/test.org has a number of example tables (though the package itself does not use composition). 3. Typing using TeX input method will produce composed glyphs. The same if you set org-pretty-entities to t and then type \alpha, \beta, etc in Org buffers. 4. Composing long spans of text might be a reasonable edge case to test. --=20 Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
