Below is my code

cat("\U30C1", "\U30A7", "\U30C3" , "\U30AF" , "\U30A4" , "\U30F3" , "\U30ED" , "\U30D3" , "\U30FC")

When it is run in R studio is looks like this (which is how it is supposed to)

チ ェ ッ ク イ ン ロ ビ ー

However when I knit it to PDF it outputs like this

U+30C1 U+30A7 U+30C3 U+30AF U+30A4 U+30F3 U+30EDU+30D3 U+30FC

Does anyone know how to fix this so the Japanese symbols can be on the PDF?

    Some poking around suggested that switching to the xelatex engine might be necessary and perhaps using a different base font (e.g. https://stackoverflow.com/a/39207334/1457051) – hrbrmstr Nov 06 '18 at 11:41
