JIS X 0201
From Just Solve the File Format Problem
JIS X 0201 is an 8-bit encoding for Japanese text. Character codes 0-127 are identical with ISO 646-JP. Character codes 128-255 provide encoding for Katakana characters and some Japanese punctuation. This allows phonetic rendering of Japanese but omits the Hiragana and Kanji scripts, which are used in normal writing.
