Not that I know of, but maybe we could add a filtering feature to
ttbtest: in one way, given some text on stdin, it produces dots on
stdout, either unicode braille dots if the locale permits it, or else
standard nabcc brf. The other way around to convert back dots to text.
That way you could do want you are asking (e.g. from german braille to
french braille) this way:

ttbtest -f de < file.de | ttbtest -F fr > file.fr

Note that if you are in a utf-8 environment, you can also just use

ttbtest -f de < file.de > file.utf-8

and file.utf-8 will be readable whatever the table in use, as it will
contain plain braille patterns.
