A. Administrative | |
| 1. Title | Proposal to encode Tibetan Extensions in ISO/IEC 10646 |
| 2. Requester's name | China, Ireland, United Kingdom |
| 3. Requester type | National body request |
| 4. Submission date | 1997-12-08 |
| 5. Requester's reference | JTC1/SC2/WG2 N1374, N1378. The characters in this proposal were requested by China, Ireland, and the United Kingdom in N1378. These could not be included because of balloting procedures on the PDAM for Tibetan, and it is recorded in the minutes of the SC2/WG2 meeting in Copenhagen that such additions should be part of a subsequent application. This is that application. |
| 6a. Completion | This is a complete proposal. |
| 6b. More information to be provided? | No |
B. Technical -- General | |
| 1a. New script? Name? | No. |
| 1b. Addition of characters to existing block? Name? | Yes, to Basic Tibetan, and addition of a new block, Extended Tibetan. |
| 2. Number of characters | 18 to Basic Tibetan and 35 to Extended Tibetan |
| 3. Proposed category | Category A |
| 4. Proposed level of implementation and rationale | Level 2 as for Tibetan already |
| 5a. Character names included in proposal? | Yes |
| 5b. Character names in accordance with guidelines? | Yes |
| 5c. Character shapes reviewable? | Yes |
| 6a. Who will provide computerized font? | Michael Everson, Everson Gunn Teoranta |
| 6b. Font currently available? | Michael Everson, Everson Gunn Teoranta |
| 6c. Font format? | TrueType |
| 7a. Are references (to other character sets, dictionaries, descriptive texts, etc.) provided? | No. |
| 7b. Are published examples (such as samples from newspapers, magazines, or other sources) of use of proposed characters attached? | No |
| 8. Does the proposal address other aspects of character data processing? | No |
C. Technical -- Justification | |
| 1. Contact with the user community? | Yes. |
| 2. Information on the user community? | Apart from the use of Tibetan as a language of daily life, the scholarly community, particularly researchers at SOAS in London, have indicated their need for the extensions proposed here. |
| 3a. The context of use for the proposed characters? | Most of the extensions are for specialized printing of Tibetan, i.e., not for ordinary newspapers (which is why Extended Tibetan is proposed). The characters to be added to Basic Tibetan are considered to be necessary for the normal production of Tibetan texts, though some of them are used in specialized "unusual" stacks. |
| 3b. Reference | N1374, N1378 |
| 4a. Proposed characters in current use? | Yes. |
| 4b. Where? | In Tibetan literature. |
| 5a. Characters should be encoded entirely in BMP? | Yes. |
| 5b. Rationale | Tibetan is in the BMP. |
| 6. Should characters be kept in a continuous range? | Yes |
| 7a. Can the characters be considered a presentation form of an existing character or character sequence? | No. |
| 7b. Where? | |
| 7c. Reference | |
| 8a. Can any of the characters be considered to be similar (in appearance or function) to an existing character? | No |
| 8b. Where? | |
| 8c. Reference | |
| 9a. Combining characters or use of composite sequences included? | Yes |
| 9b. List of composite sequences and their corresponding glyph images provided? | No, but it will be provided at PDAM time. |
| 10. Characters with any special properties such as control function, etc. included? | Yes, at 0FF9-0FFF in this proposal. See many, many papers on Tibetan encoding, including papers by Peter Lofting. |
D. SC2/WG2 AdministrativeTo be completed by SC2/WG2 | |

| 2. Status (list of meeting number and corresponding action or disposition) | |
| 3. Additional contact to user communities, liaison organizations etc. | |
| 4. Assigned category and assigned priority/time frame | |
