misunderstood you, thought you talked about external tools / scripts

Thats exactly what i want to prevent. The escapes will be (un)escaped at
I/O time and vice versa. The inner tla logic never sees escapes!
Whenever it reads something which might have escapes it is first
unescaped (right after the tokenization step).
Whenever it writes something it is escaped (prior assembling output
lines).

I/O the clean layer where such things can be done, the code which needs
to be changed is easy to spot and it is nonintrusive to the inner tla
logic and easy to debug. Besides that there are much more spots of
maintainace which need to handle the escapes when it is delayed to
lower/later layers, sorry I don't want to do that.
