I want to display and edit simulated Braille.
OS X has had Braille fonts since Tiger, so all I need to do is pass
the
correct Unicode codes to NSTextView, except the Braille fonts are
proportional spaced, and I need monospaced.
There is a Unicode entity called BRAILLE PATTERN BLANK which could
double as
a space, except that NSTextView doesn't treat it as white space.
It's not
used for finding word breaks.
I've been looking for solutions along the lines of:
Override the character spacing of a font, or
Override the definition of white space, or
Override the word break algorithm.
but I haven't found documentation for any of that.
Any suggestions?
Many thanks.
James
