Proposed update of UTS #46, for Unicode domain names

UTS #46 "Unicode IDNA Compatibility Processing"
<http://www.unicode.org/reports/tr46/tr46-18.html> is used by many
applications to support internationalized domain names with non-English
characters. The proposed update to Version 10.0 regenerates the UTS #46
data files based on new additions to the Unicode repertoire, and adds
three new parameters for processing: CheckHyphens, CheckBidi, and
CheckJoiners. These parameters allow implementations to reflect current
practice in browsers. The note about the use of IDNA2008 now includes
the number of "missing" IDNA2008 characters (26,568), and is reworded
for clarity.

There are two review notes requesting feedback on the use of Joiner
characters.

For details and information about how to provide feedback, please see
Public Review Issue #347 <http://www.unicode.org/review/pri347/>.
