ds Reader minor issue

Hi i have been using ds Reader on my acekard, it works fine apart from an annoying issue where it won't show "speech marks", instead it shows them as an inverted L or a square, i have tried a few different fonts to try and see if this would help but none have work, any ideas on this ?

Quotation marks?

yeah...." speech marks / quotation marks" won't show up

Save the text files as "text document - MS-DOS format".
