As I remember, accented letters are among these: there are so-called
"combining" characters that allow the letter and the accent to be specified
separately, as well as characters that represent the accented letters as
single, combined entities.

One solution to this is to "normalize" the Unicode string before it reaches
the braille translation functions, so that only one representation is ever
used for those characters. Techniques for doing this, and very likely working
code as well, are available, but this is well outside my area of knowledge.
The W3C has published on this subject as well.

Would this still be useful even if a normalization algorithm is implemented as
suggested above? This is an open question; I don't pretend to have an answer.
