I'd like to have an opinion about why this

        chart (for example)

        

        describes two code points 09E4 and 09E5 as<reserved>,

        without

        

        assigning any glyph, but still associating them with other

        punctuation

        

        signs in another script. 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.

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"
