"Not everyone has …" is not a reason for everyone's Lua to be bloated
with a feature few people need.  The suggestion made in another post,
to provide a module that has a function (actually, why not name the
function `_u`?) such that 

_u[["A smiley: \u263a, an en-dash: \u2013, an ellipsis: \u2026"]]

returns

"A smiley: ☺, an en-dash: –, an ellipsis: …"

seems to make a lot more sense.
