Dear Bastien DUMONT and John MacFarlane,

Thank you very much for your reply.

Regarding issue 1, I will use Unicode curly quotes instead of strait quotes 
to avoid misinterpretation.

Regarding issue 2, I tried marking the English text as [That person said, 
"Hello, world!"]{lang=en}, but the result was the same (i.e., quotes are 
typeset with the Japanese font instead of the English font). I also tried 
Unicode curly quotes.

I have confirmed that "pandoc input.md -t input.tex" generates a code as 
expected as follows:
\foreignlanguage{english}{That person said, ``Hello, world!''}

Therefore, this is puzzling to me...


Best regards,
Shigeru KOBAYASHI
