>Description:
When give two files containing valid UTF-8 text characters, diff
simply reports "Files x and y differ". Note that this happens
even if your locale is correctly set as UTF-8. Diff from 7.X
does not do this. This breaks scripts which are relying on diff
to produce the differences in the text files. In the test I tried
the actualldiffering lines were plain ASCII - the UTF-8 characters
were elsewhere in the file.
>How-To-Repeat:
Create two UTF-8 files, change one, diff the pair and observe
that diff does produce the differences.
>Fix:
'diff -a' provides a workaround
