fully untested:
function utf8.find(s, ...)
local a, b = s:find(...)
return utf8.len(s, 1, a), utf8.len(s, 1, b)
end
function utf8.sub(s, a, b)
return s:sub(utf8.offset(s, a), utf8.offset(s, b))
end
function utf8.reverse(s)
local l, t = utf8.len(s), {}
for p, c in utf8.codes(s) do
t[l] = c
l = l -1
end
return utf8.char(table.unpack(t))
end
