Bruno さんからこんな問い合わせが来ました。 次からは issue ML も送信先 (cc:) に含めるようにします…。 -- Hironobu Yamashita ---------- Forwarded message ---------- From: Bruno Le Floch <blflatex@gmail.com> Date: Wed, 16 Jan 2019 23:57:47 +0100 Subject: Re: regexpatch: error on (u)pTeX with Japanese char To: Hironobu Yamashita <h.y.acetaminophen@gmail.com> Cc: latex-team@latex-project.org Hello Hironobu, Enrico forwarded some simple code of yours to determine if a character is jp or not in ptex/uptex. Do you know why there are two separate primitives \catcode and \kcatcode? It seems that their functionality could have been combined into a single one. We may decide to provide only one higher-level expl3 function that would call either of these as needed. I may be missing some reason why \catcode and \kcatcode are separate. Of course the documentation is hard to read for non-Japanese speakers. Best regards, Bruno
