Hi.

Japanese document class (e.g. ltjsarticle) reported error
in this document like
https://tex.stackexchange.com/questions/222320/russian-in-document-with-japanese-as-main-language-lualatex-ltjsarticle
or generating PDF with Pandoc from Markdown document.
("pandoc --pdf-engine=lualatex -V documentclass=ltjsarticle document.md -o document.pdf")

Then reported this error.

```

! Number too big.
ltj@@jfont ->luafunction ltj@@jfont at inner

```

Thanks.
