I looked something up at Google a few minutes ago and found that today Google has Braille letters in its display in a graphic.
I did actually try to open http://www.google.com yet it opened at http://www.google.co.uk so I do not know if this is a worldwide feature today at Google or just for the United Kingdom.
Clicking on the graphic carries out the following search.

Readers may know that Braille character patterns are included in Unicode.
