"ANK stands for Alphabet, Numerals, and Katakana. The ANK fonts use the `Kana-8' encoding. The lower half of each font uses the JIS Roman encoding, and the upper half contains half-width Katakana. Half-width Katakana are simplified Katakana that may need to be equipped with diacritical marks. The diacritical marks are included in the encoding, as separate characters."
