Isn't part of the issue that one cannot represent some of the target indicators
in ASCII? How, for example, does one represent bolding, italics, or underlining
in a text file?
My understanding is that UTD is also a means of passing much more rich
information to the translator.

My only question of that is, if the case for doing it in liblouis is so strong,
why have so many done their own hack work arounds outside liblouis rather than
fixing liblouis and submitting a patch? What is it that everyone is missing in
the fixing liblouis solution?
There must be something in the external solution idea which has lead people
that way.
I am suggesting that the increased complexity of the external solution cannot
be too big as it seems preferable compared to working with liblouis code.
Additionally I would suggest that having to work in C increases the difficulty
as one looses some of the features of higher level languages (eg. string
manipulation libraries, object orientation, etc).
