Subject: Clarification of Action Item 106-A69
The UTC did not adequately answer the issue in PRI# 82. The top-then-bottom vowel ordering was merely an example, and other combinations of vowel signs also exist (for example, left-to-right). Please can the UTC clarify the ordering of any combination of vowels. I personally recommend the ordering "left, top, bottom, right" which is in keeping with the ordering already used in canonically equivalent vowel signs in the ISCII-based scripts. Could the UTC also clarify whether this is to be extended to all ISCII-based scripts in Unicode, or just Gurmukhi. Clarification in the Unicode 5.0 standard book would also be desirable.
The UTC may wish to review documents L2/05-344, L2/06-020 and comments on PRIs L2/06-031 .
