Russian in document with Japanese as main language (LuaLaTeX + ltjsarticle)

Question

I need to use some Russian text fragment in ltjsarticle class, which provides the Japanese settings like Japanese caption for LuaLaTeX.

In the current MWE,

• There are big intervals between Russian letters.
• There is no hyphenation.
• The table name becomes to Russian, however the main language in my document is Japanese, so I need to keep the Japanese names (there is no Japanese language in babel or polyglossia packages, so I can't to assign as \setmainlanguage neither Japanese and Russian).

\documentclass[a4paper]{ltjsarticle} 
\usepackage{luatexja-fontspec}

\setmainjfont[BoldFont=HGMinchoB]{MS Mincho}
\setsansjfont[BoldFont=KozGoPro-Bold]{MS Gothic}

\setmainfont[Ligatures=TeX]{TeX Gyre Pagella}
\setsansfont[Ligatures=TeX,Scale=MatchLowercase]{TeX Gyre Heros}
\usepackage{fontspec}

\usepackage{array}
\usepackage{booktabs}

\usepackage[russian]{babel}
\usepackage{multicol}

Теперь русский. The letters is too wide, isn't it?

\begin{multicols}{3}
Now the hyphenation test. There are no the [-] symbol, isn't it? Тест переносов. Так как осуществляется набор в три колонки, то и вероятность того, что произойдёт перенос слова, значительно возрастает.
\end{multicols}

I know about some commands like \setotherlanguage or \newfontfamily\cyrillicfont, but I didn't desired result with these commands, too.

• Note: Maybe you have not got the fonts. Please replace fonts commands, if so.
• Note: If you need ltjsarticle class, you can get it here.

Answer 1

Reading the documentation reveals that characters are classified in “ALchars” and ”JAchars” and that Cyrillic is assigned to “JAchars”.

Just reassign:

\ltjsetparameter{jacharrange={-1, -2, +3, -4, -5, +6, +7, +8}}

(the standard declaration has +2, see section 4.1 of the documentation).

Of course you have to use a font that supports Cyrillic, which TeX Gyre Pagella doesn't.

There is no real integration of luatexja with babel, so doing \usepackage[russian]{babel} overrides all settings. As far as I can see, only Japanese and English are supported.

You can correct this by doing \usepackage[russian,english]{babel}. If you need longer passages in Russian, with correct hyphenation, use

\begin{otherlanguage*}{russian}
...
\end{otherlanguage*}

For shorter parts \foreignlanguage{russian}{...} can be used (or nothing at all for a single word, that however won't be hyphenated).

I provide some fixes for babel in luatexja, but be prepared to find other places where something can go wrong.
