Hi Lloyd: That is what I also found after a couple of days googling. I dont know where it all is going but it is well beyond my ability to script anything useful and likely not even possible without external apps. MathJax is one option but even that is not a complete implementation yet. So, as far as I am concerned, this is not a potential scripting project under WindowEyes and I am off to look at other possible projects - likely a new website for another blind group. Later and thanks to everyone who chimed in concerning this topic.

Much math material is presented on the web as pictures of the equations. Other material is written out using the laTeX language, which is related to the TeX typesetting language. Other material is written using a web standard called MathML, mathematical markup language. MathML was supported in Internet Explorer by means of the MathPlayer program from Design Sciences. This primarily output speech rather than correctly coded braille. MathPlayer is a plug-in to IE, and was a great solution until Microsoft decided to disable plug-ins at IE version 10. Trying to solve this problem is not just a matter of putting some extended characters into a dictionary. It is, once again, like trying to build your own browser that interprets JavaScript, various flavors of HTML, various styles of coding, etc. Part of MathML is being interpreted by VoiceOver on the iDevices starting with iOS version 7. Applications that can read ePub 3 publications are supposed to be able to interpret MathML, but most of this is not working yet.You shlould also look up information about MathJax, and the program that works within EdSharp to help you interpret LaTeX (pronounced "La Tech) expressions.

For example, what about the Calcus symbols or the standard ones often used in describing the EM Field variables? Has anyone ever done anything trying to write a script for say either a book reader or even internet pages to make the equations read well? I have been looking at many sites lately related to quantum mechanics and light and found many, all?, sites using equations where either I get a line of characters that dont make sense to me or a blank space where a given symbol, image?, is located within the equations. I know there are third party packages that might, repeat might, work perhaps with braille but why cant a screen reader like WindowEyes with it's attendant dictionaries be used to read these pages or books? I am wondering if the pages or software could be scripted in some way to make advanced math and science equations readable with WindowEyes. Just a consideration at this point and not even a thought of being a scripting project but just the question of why it hasent been done by the screen reader companies and if anyone has ever tried to script something to enable it for WindowEyes in the past.
