Hi Rob,

For documents which I intend to export to multiple targets, PDF and HTML
specifically, I use lualatex instead of pdflatex for the PDF target.  I
insert the specific unicode characters directly in my text.  I then
include the following in my org file to ensure that the LaTeX handles
the unicode characters correctly:

#+latex_header: \usepackage{newunicodechar}
#+latex_header: \newunicodechar{α}{\ensuremath{\alpha}}
#+latex_header: \newunicodechar{δ}{\ensuremath{\delta}}
#+latex_header: \newunicodechar{Δ}{\ensuremath{\Delta}}
#+latex_header: \newunicodechar{∈}{\ensuremath{\in}}
#+latex_header: \newunicodechar{ν}{\ensuremath{\nu}}
#+latex_header: \newunicodechar{ϕ}{\ensuremath{\phi}}
#+latex_header: \newunicodechar{ï}{\"i}%"}
#+latex_header: \newunicodechar{±}{\ensuremath{\pm}}
#+latex_header: \newunicodechar{ρ}{\ensuremath{\rho}}
#+latex_header: \newunicodechar{√}{\ensuremath{\sqrt}}
#+latex_header: \newunicodechar{≻}{\ensuremath{\succ}}

This allows the characters to go straight through when exporting to HTML
but get converted to specific LaTeX when exporting to PDF.

I used this, for instance, for my recent book: https://tiny.cc/nl5yuz
This book, written in org with babel, had a lot of Julia code and one of
the nice things about Julia is you can use unicode characters for
variable and function names.  But exporting then becomes more

For program listings, I had to also do the following:

#+latex_header: \usepackage{textgreek}
#+latex_header: \lstset{literate=
#+latex_header: {Δ}{{\textDelta}}1
#+latex_header: {δ}{{\textdelta}}1
#+latex_header: {∈}{{$\in$}}1
#+latex_header: {ï}{{\"i}}1%"}}
#+latex_header: {α}{{\textalpha}}1
#+latex_header: {β}{{\textbeta}}1
#+latex_header: {γ}{{\textgamma}}1
#+latex_header: {μ}{{\textmu}}1
#+latex_header: {π}{{\textpi}}1
#+latex_header: {ν}{{\textnu}}1
#+latex_header: {ω}{{\textomega}}1
#+latex_header: {ρ}{{\textrho}}1
#+latex_header: {ϕ}{{\textphi}}1
#+latex_header: {₁}{{$_1$}}1
#+latex_header: {₂}{{$_2$}}1
#+latex_header: {≥}{{$\ge$}}1
#+latex_header: {≤}{{$\le$}}1
#+latex_header: {≠}{{$\ne$}}1
#+latex_header: {±}{{$\pm$}}1
#+latex_header: {≻}{{$\succ$}}1
#+latex_header: }
