+% \subsection{Emulating \tn{Ucharchar} in \LuaTeX{}}
+%
+% Expandably creating character tokens can be done in macros but for the
+% full Unicode range requires engine support in practical terms. That is
+% available in \XeTeX{} as \tn{Ucharcat} but in \LuaTeX{} some Lua code
+% is required. That is set up here, following the model above. Note that
+% we do not try to emulate the syntax of the primitive (doable with \LuaTeX{}
+% 0.80 or later, but not required by our use case).
+%
+% One minor wrinkle is that a catcode table is needed to return values.
+% For format mode, long-term we can simply take an arbitrary one and make
+% sure this is never allocated. In package mode use the same approach
+% (and table) as \pkg{ucharcat}: look for an allocator and use it if available,
+% or use a table unlikely to clash with any other use. We use the same table
+% as \pkg{ucharcat} but as this is \enquote{disposable} we are safe.
