Four Arabic Pegon Characters

[eggrobin]

[172-C3] Consensus: Accept the following four characters for a future version of the standard, with property values as given in L2/22-116:

U+0897 ARABIC PEPET
U+10EC2 ARABIC LETTER DAL WITH TWO DOTS VERTICALLY BELOW
U+10EC3 ARABIC LETTER TAH WITH TWO DOTS VERTICALLY BELOW
U+10EC4 ARABIC LETTER KAF WITH TWO DOTS VERTICALLY BELOW

(Reference: L2/22-116 and section 4b of L2/22-128)

[176-C15] Consensus: The UTC approves the ArabicShaping.txt entries in L2/23-160 item 2.1 (a), replacing those recommended by L2/22-116 and previously approved in UTC-172-C3.

[176-C17] Consensus: The UTC approves the change of canonical combining class for U+0897 ARABIC PEPET to ccc=230, from ccc=0 as approved by UTC-172-C3.

ArabicShaping.txt has issues with Joining_Type of the dal-like character and the schematic names of all three.

I think it should be:

# Arabic Extended-D Characters
10EC2; DAL WITH TWO DOTS VERTICALLY BELOW; R; DAL
10EC3; TAH WITH TWO DOTS VERTICALLY BELOW; D; TAH
10EC4; KAF WITH TWO DOTS VERTICALLY BELOW; D; KAF

I think it should be:

# Arabic Extended-D Characters
10EC2; DAL WITH TWO DOTS VERTICALLY BELOW; R; DAL
10EC3; TAH WITH TWO DOTS VERTICALLY BELOW; D; TAH
10EC4; KAF WITH TWO DOTS VERTICALLY BELOW; D; KAF

Yes, but with "TWO" replaced by "2" and "VERTICAL" preceding the digit. "DAL WITH VERTICAL 2 DOTS BELOW" etc.

See also issue #454 for catching issues in the schematic name.

Checked consistency with Ken’s UnicodeData-16.0.0d6.txt and LineBreak-16.0.0d2.txt.
