+# We used to ask for harfbuzz-icu here, that is, we called

+# actually used the ICU support builtin to harfbuzz; Jonathan Kew had a
+# theory many years ago (private email, 21 October 2009) to switch xetex
+# to using that, and thus eliminate the need for xetex to link with icu,
+# but it never came to fruition. So, since LuaTeX (2019) wants harfbuzz
+# without icu, back to just harfbuzz
