In consultation with the area director, issues were raised concerning  
the consensus on the use of Latin small letter sharp S and Greek small  
final sigma as PVALID in IDNA2008.

I have copied the working group on a request for opinion from the  
Unicode Technical Committee.

By this message, I request a response from the Working Group on the  

Should Latin Small Letter Sharp S and Greek Small Letter Final Sigma  
be PVALID in IDNA2008 or not:

Please Respond by choosing among the following:

(1) Both characters should be PVALID
(2) Both characters should be DISALLOWED
(3) Only Latin Small Letter Sharp S should be PVALID
(4) Only Greek Small Letter Final Sigma should be PVALID

Choices (3) and (4) create additional complexity in dealing with  
IDNA2003 and IDNA2008 disparities

During the Last Call, a number of objections were raised with regard  
to choice (1) and this led the Area Director to question the rough  
consensus that the WG submission to IESG claimed.

It will be much appreciated if all working group members would respond  
by December 8.
