Proposal for enhancements to UTS#46 for
next Unicode version
1. We've heard from some people that it
would be useful to indicate whether a character is allowed in
IDNA2008 or not, and whether a test case is.
Possible syntax for the mapping table:
v6.0
00B6..00B7 ; valid # 1.1 PILCROW SIGN..MIDDLE DOT
00B6..00B7 ; valid ; notIDNA2008 # 1.1 PILCROW SIGN..MIDDLE DOT
Possible syntax for the test file:
v6.0
B; xn--53h; ☕; xn--53h ; notIDNA2008
2. It would be useful to generate a
more comprehensive set of test cases, like we do for collation.
It could include one sample for:
-
each assigned character (a
sample in the case of large scripts)
-
each multi-character nfd and
nfkd decomposition
-
+ an interior combining mark
-
+ a trailing combining mark
