Last Call on Unicode 11.0 Review

stopwatch imageThe beta review period for Unicode 11.0 and related
technical standards will close on April 23, 2018. This is the last
opportunity for technical comments before version 11.0 is released in Q2
2018. Implementers and interested parties are encouraged to download
data files, review proposed updates, and submit comments.

Unicode 11.0 adds seven new scripts, including Hanifi Rohingya, 66
additional emoji characters, including four new components for hair
color (for a total of 157 emoj sequences
<http://www.unicode.org/emoji/charts-11.0/emoji-released.html>). The set
of Georgian Mtavruli capital letters has been added to support modern
casing practices.

Annexes and two Unicode Technical Standards have significant
