I have a question regarding prohibited characters.

I was looking at the nameprep document
(http://www.ietf.org/internet-drafts/draft-ietf-idn-nameprep-00.txt)
and noticed that the characters:

U+0027	APOSTROPHE
U+0028	LEFT PARENTHESIS
U+0029	RIGHT PARENTHESIS
U+002A	ASTERISK

are not listed as prohibited characters.

Here are a few more characters similar to prohibited characters (or to
the 4 characters above):

U+2018	LEFT SINGLE QUOTATION MARK
U+2019	RIGHT SINGLE QUOTATION MARK
U+201B	SINGLE HIGH-REVERSED 9 QUOTATION MARK
U+201C	LEFT DOUBLE QUOTATION MARK
U+201D	RIGHT DOUBLE QUOTATION MARK
U+201E	DOUBLE LOW-9 QUOTATION MARK
U+201F	DOUBLE HIGH-REVERSED-9 QUOTATION MARK
U+2027	HYPHENATION POINT
U+2032	PRIME
U+2034	TRIPLE PRIME
U+2035	REVERSED PRIME
U+2036	REVERSED DOUBLE PRIME
U+2037	REVERSED TRIPLE PRIME
U+2043	HYPHEN BULLET

U+2217	ASTERISK OPERATOR

(Maybe the whole range of punctuation characters from U+2000 - U+206F
should be prohibited?)

Should some or all of these be added to the list of prohibited
characters under section 3.5 (prohib-5:  Punctuation) of the draft?
