       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):

       -kanjistring
              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-internalstring
              Sets  the  internal  Kanji code.  The string can be either euc, and sjis.  For (e-)upTeX, uptex is
              also allowed.

       Deletions:
