It might, except conventions vary and there is usually more than one convention for any
given script. I think the dotted circle is a fine convention and would be happy to see it
used everywhere, but publishers and lexicographers etc. have their own established
conventions, so we should try to document and support them.

SBL Font Foundation members have reported four conventions: a circle (non-dotted), a
square, a baseline stroke and a blank space. The baseline stroke is the most problematic,
because I'm not sure how this should be encoded (some people have suggested the Arabic
tatweel character).

A note in the individual script section of the Unicode book would certainly be welcome.
