NAME
       ptex, uptex, eptex, euptex - Japanese "Publishing TeX"

SYNOPSIS
       ptex [options] [&format] [file|\commands]

DESCRIPTION
       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.

OPTIONS
       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.
