LuaTeX-ja wiki

We will move to GitHub (Wiki (English)). This site (and repository) on OSDN will be kept as much as possible, but it may not be updated.

LuaTeX-ja is a macro package to typeset Japanese texts using Lua(La)TeX. A goal of this project is to provide an equal or superior typesetting system to ASCII pTeX, which is a traditional standard Japanese TeX engine.

Support

From LuaTeX-ja 20190926.0, Unicode block "General Punctuation" (U+2000--U+206F) are divided into character classes 4 and 9. Hence, if your old document contains a line

\ltjsetparameter{jacharrange={-3,...}}

this should be changed to

\ltjsetparameter{jacharrange={-3,-9,...}}

If you have questions or recognize bugs/have feature requests, we would like you to create an issue.
