Kimsan, 

           When I did a DuckDuckGo search on, "What is UEB Braille," a number of sites that show promise for what you're seeking showed up, but I cannot know exactly how the various materials will interact with JAWS without trying it.  The UEB pages at brailleauthority.org, uebonline.org, and the Wisconsin Center for the Blind and Visually Impaired, all look like possible places to start.
