It's a very common Vietnamese surname so it's not unheard of in France though, it's often pronounced as "lé", maybe because it's the right pronunciation (I don't know) but in any case it makes it immediately different from the common word "le". Although when written, if that person has a typical French name like "Jean Le" there might be people who think it's been truncated indeed.
