In addition to Jean's recommendation, there is also another approach.  You can find some discussion of this here: https://tex.stackexchange.com/a/251498


Basically, you can use these options (in addition to your other hyperref options, of course):
\usepackage[pdfencoding=auto, psdextra]{hyperref}


This won't get rid of the "math shift" warnings, however.  You'll need to follow Jean's recommendation and use \texorpdfstring if you want those math shift warnings gone completely.  For example:

\section{stuff \texorpdfstring{$\omega$}{w} stuff}


Another approach altogether is to replace the math symbols in your section headings with ones from the "textgreek" package, like this:

\usepackage{textgreek}

\usepackage[...]{hyperref}

\begin{document}
...

\section{stuff \textomega stuff}% vs. the current \section{stuff $\omega$ stuff} approach
...
\end{document}

You should probably use the command
\texorpdfstring{TEXstring}{PDFstring}

See Hyperref-manualpdf p. 19 :

hyperref takes the text for bookmarks from the arguments of commands
like \section, which can contain things like math, colors, or font
changes, none of which will display in bookmarks as is.

\texorpdfstring{TEXstring}{PDFstring}
For example,
\section{Pythagoras:
\texorpdfstring{$a^2 + b^2 = c^2$}{%
a\texttwosuperior\ + b\texttwosuperior\ =
c\texttwosuperior
}%
}
\section{\texorpdfstring{\textcolor{red}}{}{Red} Mars}

I use MikTeX 2.9. Now, according to the requirements of an AIMS
journal, I should use package hyperref. I obtain 27 warnings of
the type

Package hyperref Warning: Token not allowed in a PDF string
(PDFDocEncoding):
(hyperref)                removing \omega' on input line 512.

I do not know what to do and need help. Thank you in advance.
