[Glean] Package hyperref: Token not allowed
PDFDocEncoding Warning
When we're using hyperref
to generate toc for the PDF file, we may witness this error if there are unsupported tokens in our titles:
Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding):(hyperref)
The easiest solution for this is to use \texorpdfstring{token in Tex}{string that shown in PDF toc}
.
For example:
\subsection{\texorpdfstring{$7 \times 7$}{7 × 7}, Stride 2}
