Issue with special characters

Hi,

I am using TOC and it's an awesome plugin. However, I have an issue : Some of my headings have accents (é,è, ...), thus the anchor generated is not super clean. Example here : for the heading "Sécurité", the anchor is : #toc-s-curit-. Is there a way to replace letters with accent by letters without accent (so my anchor would become #toc-securite ? 

Thanks
