+-- Explanation of locale madness:
+-- LuaTeX resets LC_CTYPE, LC_COLLATE, LC_NUMERIC to "C". That is good for

+-- environment is something else, we want to switch back to it. As of
+-- TL 2017 LuaTeX, we can inspect the user's locale with status.lc_ctype, etc.
+--
+-- For texdoc purposes, what matters is LC_CTYPE (so we don't bother with
+-- the others). For example, with the less pager, when LC_CTYPE=C,
+-- non-ASCII bytes are displayed as "<xx>", where xx is the two hex
+-- digits for the byte.

+-- See <texdoc-dev-source>/tools/Makefile for a standalone test case.
