Ah the power of emoji! To encompass even science and mythology!

other interesting combinations:
- <SUN + ZWJ + UMBRELLA + COMBINING SHADOW> = parasol
- <RAINING CLOUD + ZWJ + UMBRELLA> = parapluie
- <SUN + ZWJ + WEARING GLASSES + COMBINING SHADOW> = sun glasses
- <THUNDERBOLT+ZWJ+ANTENNA+COMBINING SHADOW> = parafoudre
Note that a "combining" shadow is not absolutely necessary, but I don't how
a shadow can exist with the object creating it and giving its form to the
The direction of the shadow does not matter (I suggest is is oriented by
default to the bottom right for LTR contexts including emojis, and to the
bottom left for RTL contexts, using Bidi controls could override this
direction). And it could easily apply to any character cluster
(transforming it into a symbol, or encoding the shadow as ignorable with
combining class 0, i.e. requiring its encoding at end of the cluster from
which it derives the shadow form to render). It would not necessarily
require new fonts (shadowing can be synthetized by text renderers from
- LATIN LETTER A + COMBINING SHADOW = shadowed letter A (the shadow to the
bottom right is a mirrored and skewed version of the letter, projected from
its natural baseline)
