It was written in English, but your MUA labeled it as being encoded
with ks_c_5601-1987. Is that a Korean charset? Non-broken MUA will
obey the header, and display it as though it was encoded with that
charset: the result is garbage.

That depends on your needs, the ways that you use the data.
I'd certainly recommend that you:
* try both ways, and study the output of EXPLAIN for the
respective queries
* read up on normalization
