🌸 SYNOPSIS 🌸

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

🎀 DESCRIPTION 🎀

pTeX (ptex) is a TeX engine with extensions for Japanese typesetting — and when I say extensions I mean the whole glow-up: features related to line breaking rules, inter-character spacing and vertical writing. 👑 It was first developed by ASCII Corporation, with the aim of providing a Japanese TeX that could actually be used for commercial publishing. very main character energy. For pTeX, the character set available is limited to JIS X 0208, namely JIS level-1 and level-2. that's the whole menu, bestie.

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. iconic behavior fr fr. 🦋

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. affectionate nickname, we love her 💅

(e-)(u)pTeX's handling of its command-line arguments is similar to that of the other TeX programs in the web2c implementation. same vibe, different engine. ✨
