I am uploading a XML file for RSS feeds, fom the link, it shows all the feeds but on IE the french word is Tobique–Mactaquac (hyphen between two words) but where RSS is shown, it does not show hyphen and displays as TobiqueMactaquac. My charset is set to UTF-8 Hyphen between these two words is shown only in IE. the link to RSS is here
Is it a hyphen or an em or en dash? If one o the two latter, you need to use the appropriate HTML entity reference rather than the literal. And just to be clear, this has nothing to do with French specifically, so you ought to edit your question.
Issue was solved after using iso-8859-1 charset on that specific page
