KS X 1001
From Just Solve the File Format Problem
KS X 1001 (Hankuk Gyugyeok Munja Pyo for Information Interchange, KS C 5601, Unified Hangul) is an encoding used primarily in South Korea to encode hangul and hanja characters. It encodes characters as two byte sequences, using only seven bits. There have been a number of revisions of the standard; the earliest ones had some single-byte characters, but the later ones use two bytes for everything except the C0 controls, whose code positions are unused except as control characters.
