To be honest, it seems only fair to me, since Lua's standard script

script file.

A regrettable precedent, perhaps? Although it's an OS feature that is
well documented and used on multiple platforms. In any case, I think the
"correct" response to this problem is...
From http://www.lua.org/manual/5.1/manual.html#pdf-load

function utf8_dofile(filename)
return assert(load(
function()
return string.gsub(
assert(io.open(filename)):read('*a'),
'^\239\187\191', '')
end,
filename
))()
end
Or something like that.
