Are these positions permanently reserved for the case where specific danda signs would be later discovered and encoded specifically in this script ? OR are they really unassigned and usable for encoding later any other kind of character ? They are for potential script-specific danda signs and closed to other kinds of characters. The annotation "<reserved>" is used for any character location that is unassigned. Most such locations are suppressed in the character names list pages for the code charts. However, if a location carries some other annotation it will be listed and <reserved> will a appear in place of the character name. Usually, the reason for having an annotation on an empty code point is because of "parallel encoding structure" somewhere else. Usually, it is because of the existence of such parallel encoding structure, that there even are empty cells in a block that are not at the end (although occasionally they exist for other reasons). However, <reserved> simply means "unassigned" not "set aside permanently for a special purpose". Given the right circumstance, the encoding committees are free to decide to reclaim such "holes" at any time, although they may be more reluctant to do that with certain types of holes compared to others. These particular open code points are probably of the kind that the committees are more reluctant to reclaim for "random" characters. A./ I think the most appropriate position for the letters coded with 09F0 (ASSAMESE RA) and 09F1 ( ASSAMESE WABBO) should have been at 09B1 and 09B3 respectively. Besides all other letters' appropriate descriptions should be like ASSAMESE/BENGALI LETTER.............. in the pdf document U0980.pdf and the page header should be Assamese/Bengali and the main webpage (Code Charts) button link should read "Assamese and Bengali" Regards DR
