I have done the same, on a clean Emacs init. Warning appears.

And in *Messages*:

PDF file produced with warnings: [unicode character(s) not set up for use with 
pdflatex. You can run lualatex or xelatex instead]

In *Org PDF LaTeX Output*:

! LaTeX Error: Unicode character 你 (U+4F60)
               not set up for use with LaTeX.

(this error is the one that passes as a warning in my patch when
compiled with pdfLaTeX).
