Dear Bastien DUMONT,

Thank you very much for your reply. I tried as follows and got no changes. I'm sorry if I misunderstood your suggestion.

preamble.tex:
\usepackage{fontspec}
\setmainfont{Georgia}
\setjamainfont{BIZ UDMincho Medium}
\babelfont[english]{rm}{Georgia}

input.md:
---
documentclass: bxjsarticle
classoption: pandoc
papersize: a4
---

[That person said, "Hello, world!"]{lang=en}

shell:
$ pandoc -V lang=ja input.md -o input.pdf --pdf-engine=xelatex -V pandoc -H preamble.tex

An if you put the English parts in language spans as I said and add in header-includes \babelfont[english]{rm}{Georgia}?
