The original poster might be interested in the Netconversion module
from Ocamlnet, which is designed to work with UTF-8 stored in OCaml
strings. In particular it has a function

  Netconversion.verify `Enc_utf8 s

which checks that s is a valid UTF-8 string. It also has equivalents
for String.{get,sub,length}.
