How to avoid warning messages from hyperref package in LaTex

\usepackage[unicode=true,pdfusetitle,
   bookmarks=true, 
   bookmarksnumbered=false, 
   bookmarksopen=false,
   breaklinks=false, 
   pdfborder={0 0 1}, 
   backref=false, 
   colorlinks=false]{hyperref}

\hypersetup{pdfauthor={Name}}

Use of hyperref package in a LaTex script makes the manuscript more visually understandable, but it often gives warning message like

Package hyperref Warning: Token not allowed in a PDF string (Unicode): (hyperref) removing `math shift' on input line 79.
Package hyperref Warning: Token not allowed in a PDF string (Unicode): (hyperref) removing `superscript' on input line 79.
Package hyperref Warning: Token not allowed in a PDF string (Unicode): (hyperref) removing `math shift' on input line 79.                     

Then, putting the snippet

\hypersetup{pdfauthor={Name}}

in a LaTex source file will remove the warning message or within the Lyx preamble section.
