Rationale for the attached patch: It seems that a common problem that
users have with exporting to LaTeX is unicode characters that cannot be
represented in pdfLaTeX or LuaLaTeX/XelaTeX. In the Unicode TeX engines
the warning is insidious, since the missing character warning is not
preceded by a 'warning' string.
Naturally, the added Org warnings do not solve the problem, but at least
they give some clues on how to properly adjust the document.
Best regards,
Juan Manuel

When I try the patch with a simple file like

I do not see any warnings or errors indicated.

How weird... And don't they at least appear in the *Messages* buffer?
With your example, they appear to me with pdfLaTeX, lualatex and XelaTeX
(I have used the default value of org-latex-pdf-process):

I did
1. Install your patch on top of the latest main
2. make repro
3. Open /tmp/1.org and enter
Hello. 你好.
4. C-c C-e l o
In *Messages* I see

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).

Probably something to do with my Texlive technically having Chinese
support.
I am getting
! Package inputenc Error: Unicode character 你 (U+4F60)
(inputenc) not set up for use with LaTeX.
See the inputenc package documentation for explanation.
Type H <return> for immediate help.
...
l.28 Hello. 你
好.
! Package inputenc Error: Unicode character 好 (U+597D)
(inputenc) not set up for use with LaTeX.
See the inputenc package documentation for explanation.
Type H <return> for immediate help.
...
l.28 Hello. 你好

I have fixed the org-latex-known-warnings regexp in the attached patch.
I think it should work fine now...
