Some uppercase letters are possibly translated incorrectly

[GoogleCodeExporter]

Uppercase letters that, once translated to lowercase, lose their distinguishing 
marks, will be translated as if they were regular characters.

= For example =
LATIN CAPITAL LETTER I WITH DOT ABOVE, 0130

(int)"\u0130".charAt(0) != (int)"\u0130".toLowerCase().toUpperCase().charAt(0)

Because only lowercase letters are allowed in the braille table, this character 
will be converted into a regular 'i' before translation.
