Re: On the lack of a SQUARE TB glyph

Or one could allow IDS to have leaf components that are any
characters, not just ideographic characters, and then one could have
all sorts of fun.

I do like that idea

André Schappo

That could be an appropriate extension for the kind of "grouping characters in an ideographic cell" that applies to examples like the *SQUARE TB.

The outcome of that process is by definition compatible for use with ideographs and not an open ended compositional scheme.
