Handling Unicode support in TeX as compared to Lua is like shooting
yourself in the foot with a mortar rather than with lawn darts.

I'd still very much prefer a Lua variant which defaults to uninterned
strings _until_ one uses them for indexing.  But it still beats using
TeX for string manipulation.
