Allowed characters (was: Re: Casefolding Sigma (was: Re: IDNAbis Preprocessing Draft)

[Mark Davis]

It is a small change to focus on characters in Arabic blocks.

Change A to:
[
 [:^idna=disallowed:]
 -[:^block=/(?i)Arabic/:]
]

Change B to
[[:L:][:Mn:][:Mc:][:Nd:]
-[:^isCaseFolded:]
-[:NFKC_QC=N:]
-[:di:]
-[[:block=Combining_Diacritical_Marks_for_Symbols:]
  [:block=Musical_Symbols:]
  [:block=Ancient_Greek_Musical_Notation:]
 ]
-[:^block=/(?i)Arabic/:]
]
Click on Only A and you'll get the list of characters that used to be valid
in Arabic blocks but would no longer be. Here's the URL to make it simple
for you:

http://unicode.org/cldr/utility/list-unicodeset.jsp?a=[[%20[:
^idna=disallowed:]%20-[:^block=/(?i)Arabic/:]]-[[:L:][:Mn:][:Mc:][:Nd:]-[:^isCaseFolded:]-[:NFKC_QC=N:]-[:di:]-[[:block=Combining_Diacritical_Marks_for_Symbols:]%20%20[:block=Musical_Symbols:]%20%20[:block=Ancient_Greek_Musical_Notation:]%20]-[:^block=/(?i)Arabic/:]]]


Similarly the characters "In both A and B" are at:

http://unicode.org/cldr/utility/list-unicodeset.jsp?a=[[%20[:
^idna=disallowed:]%20-[:^block=/(?i)Arabic/:]]%26[[:L:][:Mn:][:Mc:][:Nd:]-[:^isCaseFolded:]-[:NFKC_QC=N:]-[:di:]-[[:block=Combining_Diacritical_Marks_for_Symbols:]%20%20[:block=Musical_Symbols:]%20%20[:block=Ancient_Greek_Musical_Notation:]%20]-[:^block=/(?i)Arabic/:]]]
