Yes, that's correct, but we do things like use a single braille cell to mean
more than one thing and figure out which it is by context. That', for example,
is how we handle box drawing characters. Also, for another example, we can tell
based on which language we're currently reading.

Yes, it's really the very same problem. It's just a little more annoying, I
think, in braille since, if we want the 256 braille cell characters, we need to
give up 256 useful non-braille characters.

So am I! :-)
