To what degree mathematical expressions could be written in the bookmark name?
I understand that this is more limitation of pdf itself than of
hyperref or pdflatex.

When the section title contains mathematical expression it looks like
all non-English ASCII characters are stripped (even if they are Greek
letters, mathitalics becomes roman and instead of ^ (power) - (dash)
is appearing.

What one should do to preserve Greeks and ^ as a sign of power?

Thank you in advance.
