I guess an additional character property is needed for this, although
this is rather a glyph property. Perhaps some special combining
characters (FORCE DOUBLE WIDTH, FORCE SINGLE WIDTH) could be helpful
as well, at least for communication with terminal emulators.

There are also quite a few scripts which feature a combination of
simple and rather complex glyphs (the latter don't fit well into a
single-width box). Cyrillic and the Latin Serbo-Croatian
transliteration are examples, and Arabic, Devanagari, and Tibetan are
actually displayed with both single- and double-width glyphs by Emacs.
In addition, there are combining characters which substantially change
the width of the character they are applied to.
