Hi,
I am not an expert on this, but as far as I know, the following applies,
especially for back-translation:
1. The longer definition wins.
I.e. "always ed 1246" would take precedence over "always $ 1246".
2. If both definition have the same length, the first definition wins.
So, if you have "sign $ 1246" and "sign <something else> 1246", then 1246 will
always back-translate as $.
3. For definition of single characters, the Character definition itself
implicitly wins over any subsequent "always" opcodes, as it has to come first.
Concerning included files, I suppose they are included at the place where the
include statement occurs. So, if opcodes in an included file take precedence, I
would think it is because you generally make include statements near the top of
a file. For the same reason, I include the braillecodes.cti file at the bottom
of my character definitions. Otherwise, everything will back-translate to
Unicode Braille symbols (u+2800-u+28ff).
Where there might be any ambiguity, perceived or real, I would recommend the
use of "noback" and "nofor". This is also a good idea if you use opcodes like
"correct", "context" and pass2 etc. Apparently, these opcode have not yet been
implemented for back-translation, and so their behaviour is probably not
predictable.

Some more beginner questions.
In chardefs.cti there are a number of definitions for dots 4-1, for example:
lowercase \x00E0 4-1 LATIN SMALL LETTER A WITH GRAVE 0061 0300 LATIN lowercase
\x00E1 4-1 LATIN SMALL LETTER A WITH ACUTE 0061 0301 LATIN
How should this be interpreted? How can 4-1 be both à and á ?
Confusedly yours,
Harri
