In MOONSTORM I indicated Imperial vs. clanner names via spacing - this wouldn't exist in today's Hangeul, but in Space Hangeul, who knows. Also made it easier for the reader to differentiate since the book's written in English anyway.

Oh, I had picked up there were differing naming conventions but not what they specifically were, clever

Likelier is imperials using hanja and clanners using Hangeul or v.v. but that'd be tough in English. My experience is (usually white American) dumbasses complain if you put in too much linguistic context and other dumbasses complain about too little based on 0.8 years of kdrama exposure, so whatevs.
