If you are asking why Git detects files with text in UTF-16 / USC-2 as
binary, it is because Git (re)uses the same heuristic that e.g. GNU
diff (and probably also -T file test in Perl), and one of heuristics
is that if file contains NUL ("\0") character, then it is most
porbably binary (because legacy C programs for text would have
troubles with NUL characters).

That probably doesn't help you any...
