I made a text box and tried typing some text with Times NR so I could see what I'm typing. But when I tried changing the font to any of the Braille fonts they just appeared as boxes. How do I use braille in my photobook?
"Braille" is not simply "A..Z, but then drawn as dots". All Braille characters have a Unicode of their own: http://unicode.org/charts/PDF/U2800.pdf, and, as explained on Wikipedia (Braille Patterns - Wikipedia, the free encyclopedia), they do not immediately 'translate' to a single character.
So the answer is, you should not type text, you should insert Braille characters. The font is behaving as it should.
You can use Find/Change to change one character at a time (after all, you won't need all of them), or ask someone in the Scripting Forum to write you a custom script. Make sure to provide a list of character translations as well.
