I have the same problem. I use Windows 7 and Firefox. Most stories open with strange symbols in place of single and double quotation marks. I can fix it by clicking on the View menu, then Character Encoding. Most stories have preselected Unicode (UTF-8). If I click on one of the other choices such as Western (ISO-8859-1) the symbols are instantly replaced with the correct symbols. However, the change does not stick. When I go to the next chapter I have to do those steps again. I know this fix works, but I don't know what it means, if you know what I mean. Still researching. Hope this helps a little.
