patch to improve documentation on strings handling of unicode

[John Heidemann]

The attached patch makes it explicit that strings handles Unicode
by adding the word "unicode" to the documentation.

Please consider this patch for future releases so Unicode-interested
folks aren't forced to Google and the source code to match "encoding"
with "Unicode".

The patch is relative to binutils.texi 1.127, what is current in CVS as
of today.

Thanks,
   -John Heidemann
