I experience problems typesetting mathematical expressions. I cannot
find anything as good as the unicode-math package for lualatex.
Consider generating a preview of this fragment using pdflatex versus lualatex:
\[ ∫₀¹ 𝐟(σ) dσ \]
Isn't unicode-heavy formulas a way to rely on preview feature in less
degree? I have no idea if journals accept papers typed this way.
Some time ago I was told that \usepackage[utf8x]{inputenc} is obsolete
and should not be used any more. It is true, but I have realized that it
is not full truth. utf8x is able to handle some math while utf8 can not
do it at all.
I have found unicode-math-input.sty that may handle your specific
example in PdfLaTeX. At first glance it is more powerful than utf8x, but
it does not allow e.g. text Greek α. It forces math mode for it.
