This is maybe caused by PDF viewer you use, I don't get graves using
Acrobat Reader or pdftotext.

Grave character is used to input quotes, ie. ``hello'' will print
correct English quotes, so it would be error to get anything else in a
text. You can use \`{} command to get grave, or better


and then use \textgrave in the document. this works in pdflatex as
well as in tex4ht.
