PDFDocEncoding (PD1):

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\section{\texorpdfstring{}{\textalpha}}
\end{document}

! Undefined control sequence.
<argument> \textalpha 

PDFDocEncoding doesn't support alpha. However beta is indirectly
supported by \ss. Best approximation for alpha is probably "a":

\documentclass{article}
\usepackage{hyperref}
\DeclareTextCommand{\textalpha}{PD1}{a}
\begin{document}
\section{\texorpdfstring{x}{\textalpha}}
\end{document}

No errors or warnings.


Unicode (PU):

\documentclass{article}
\usepackage[unicode]{hyperref}
\begin{document}
\section{\texorpdfstring{}{\textalpha}} 
\end{document}

No errors or warnings.
