       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.


       -enc   In this version of (e-)(u)pTeX, encTeX extensions are not available.


       tex(1), etex(1).
