I think that on Monday I'll try removing the bit of code that replaces
all characters less than 0x20 with space and see what happens.
The code semantic action handles preformatted text, but uses computer
Braille. A similar action in which the translation table can be
specified wouldn't be hard. I can do that.
The problem with buffer overruns in utd is that one must also account
for index values. For a very big character buffer you would need a very
big buffer to handle the index values. Maybe we will do something like
this eventually, but I don't think it's a priority.
