We need a way to get ISO 15924 > script tags from Emacs. The same mismatch also prevents Syriac text from actually shaping. Syriac shaping works in m17n with the required setup in composition-function-table and using the Meltho fonts. With Harfbuzz it doesn't work, unless I change "syriac" to "syrc" in charscript.el, just for testing of course. As a success story OTOH, Mandaic, using the Noto font, works OOTB ;-) benny
