a. This proposal is for a new script (set of characters): NO
Proposed name of script:

b. The proposal is for addition of character(s) to an existing block: Yes
Name of the existing block:
Arabic presentation form B, Arabic letter tail 0xFE73

2. Number of characters in proposal:

Is a rationale provided for the choice? Like similar characters in the Arabic script.
If Yes, reference:

5. Is a repertoire including character names provided?: Yes

a. If YES, are the names in accordance with the 'character naming guidelines' in Annex K of ISO/IEC 10646-1? Yes
b. Are the character shapes attached in a reviewable form? Yes

6. Who will provide the appropriate computerized font (ordered preference: True Type, PostScript or 96x96 bit-mapped format) for publishing the standard? IBM Egypt

If available now, identify source(s) for the font (include address, e-mail, ftp-site, etc.) and indicate the tools used: IBM-1046 font sent by e-mail.

7. References:
a. Are references (to other character sets, dictionaries, descriptive texts etc.) provided?
This character is used by other codepages like IBM-420, IBM-1046 and IBM-864
b. Are published examples (such as samples from newspapers, magazines, or
other sources) of use of proposed characters attached? Host printed document, we can send a sample by fax.

8. Special encoding issues:

Does the proposal address other aspects of character data processing (if applicable) such as input, presentation, sorting, searching, indexing, transliteration etc. (if yes please enclose information):
Facilitate the data interchange between Unicode and legacy applications that use the 420 codepage and run on AS400 and OS390.

C. Technical - Justification

1. Has this proposal for addition of character(s) been submitted before?
No
If YES explain

2. Has contact been made to members of the user community (for example: National Body, user groups of the script or characters, other experts, etc.)?
Yes.

If YES, with whom?
The Arabic coommunity representative in IBM.
Unicode community in IBM Cupertino.
If YES, available relevant documents?

3. Information on the user community for the proposed characters (for example: size,
demographics, information technology use, or publishing use) is included?
Reference:
All the Arabic speaking countries, using IBM Arabic implementation.

4. The context of use for the proposed characters (type of use; common or rare)
Reference: Common.

5. Are the proposed characters in current use by the user community?
If YES, where? Reference:
Yes, on all the Host legacy applications running on S390 and AS400.

6. After giving due considerations to the principles in N 1352 must the proposed
characters be entirely in the BMP? Yes
If YES, is a rationale provided? Yes
If YES, reference: It needs to be available in the UCS range, and within the Arabic presentation forms-B characters block. For Arabic data interchange compatability with existing data.

7. Should the proposed characters be kept together in a contiguous range (rather than
being scattered)? N/A

8. Can any of the proposed characters be considered a presentation form of an existing
character or character sequence? No
If YES, is a rationale for its inclusion provided?
If YES, reference:

9. Can any of the proposed character(s) be considered to be similar (in appearance or function) to an existing character? No
If YES, is a rationale for its inclusion provided?
If YES, reference:

10. Does the proposal include use of combining characters and/or use of composite sequences (see clause 4.11 and 4.13 in ISO/IEC 10646-1)? No
If YES, is a rationale for such use provided?
If YES, reference:

Is a list of composite sequences and their corresponding glyph images (graphic symbols) provided?
If YES, reference:

11. Does the proposal contain characters with any special properties such as control function or similar semantics?
If YES, describe in detail (include attachment if necessary) No
It is a compatibility character, used only for preserving one to one mappings with legacy Arabic code pages.
