These are two different questions.  It seems that between the two of
us, we established that "UTF-16 binary" is a nonsense, and a path
that is given working-tree-encoding=UTF-16 must be treated as
holding a text file.  But that does not have direct relevance to the
other question you are asking: "is a question 'does this path have
text attribute set?' be answered with 'yes' if the path has wte
attribute set to UTF-16?"  I think the answer to that latter
question ought to be "no".

By the way, a related tangent is if it makes sense to give
working-tree-encoding to anything that is binary, regardless of the
value---I am inclined to say it is not, so the issue here is not "by
definition UTF-16 is text", but "any path that has wte set to some
enconding should be treated the same way as if the path also has
text attribute set as far as convert machinery is concerned.".
