{up\TeX\Dash Unicode version of p\TeX\ with \acro{CJK} extensions} {Takuji Tanaka} {up\TeX\ is a Unicode extension of \ASCII's p\TeX\ (a Japanese-localized \TeX). It not only improves Japanese support, but also treats Chinese and Korean characters i.e., Hanzi, Kanji, Hanja\slash Kana\slash \acro{CJK} symbols, and Hangul with Unicode. Moreover, it can process multilingual typesetting of original \LaTeX\ with \cs{inputenc\char`{utf8\char`}} and Babel (Latin, Cyrillic, Greek, etc.)\ by switching its \cs{kcatcode} tables. In this presentation, the main features of up\TeX\ will be described. }
