ptex, uptex, eptex, euptex - Japanese "Publishing TeX"
ptex [options] [&format] [file|\commands]
pTeX (ptex) is a TeX engine with extensions for Japanese typesetting, including features related to line breaking rules, inter-character spacing and vertical writing. It was first developed by ASCII Corporation, in the aim of providing a Japanese TeX which can be used for commercial publishing. For pTeX, the character set available is limited to JIS X 0208, namely JIS level-1 and level-2. upTeX (uptex) is a Unicode-enabled pTeX with extensions for better handling of CJK (Chinese, Japanese and Korean) multilingual documents. It has been developed by Takuji Tanaka since 2007. e-pTeX (eptex) is a merge of e-TeX and pTeX. e-upTeX (euptex) is a merge of e-TeX and upTeX. In the following sections, we refer to these engines as (e-)(u)pTeX. (e-)(u)pTeX's handling of its command-line arguments is similar to that of the other TeX programs in the web2c implementation.
Here we list only additions/deletions of command line options which are specific to (e-)(u)pTeX. For (u)pTeX, other options are similar to TeX. For e-(u)pTeX, other options are similar to e-TeX. Additions (supported by ptexenc library): -kanji string Sets the input Japanese Kanji code. The string can be either euc (EUC-JP), jis (ISO-2022-JP), sjis (Shift_JIS), and utf8 (UTF-8). For (e-)upTeX, uptex is also allowed. -kanji-internal string Sets the internal Kanji code. The string can be either euc, and sjis. For (e-)upTeX, uptex is also allowed. Deletions: -enc In this version of (e-)(u)pTeX, encTeX extensions are not available.
This version of (e-)(u)pTeX is maintained by Japanese TeX Development Community <https://texjp.org>. For bug reports, open an issue at GitHub repository <https://github.com/texjporg/tex-jp-build>, or send an e-mail to <email@example.com>. This manual page was written by Hironobu Yamashita.
