New Character Property for Prepended Concatenation Marks
Message ID:
The Unicode Technical Committee is seeking feedback on a proposal to 
define a new character property for the class of /prepended 
concatenation marks/, also referred to as /prefixed format control 
characters/ or, more generically, as subtending marks. Characters in 
that class include U+0600 ARABIC NUMBER SIGN and U+06DD ARABIC END OF 
AYAH. The new property, named Prepended_Concatenation_Mark and targeted 
for Unicode 9.0, would provide a mechanism to handle subtending marks 
collectively via properties rather than by hardcoded enumeration. A 
detailed description of the issue and how to provide feedback are given 
in Public Review Issue #310 <>. Perl Programming lists via nntp and http.
