No. Surely, Peter, I am not.
They can be and are exchanged as icons "in text", but not "as text".

"In" instruction manuals, but with most commenters pointing out,
correctly, that most such instances are embeddings of graphics

Yes. And the UTC has already had such arguments and concluded that
as yet there is insufficient reason demonstrated *to* encode
many of these icons as *characters*.

They wouldn't be "mapped" to 11581, because ISO/IEC 11581 isn't
a character *encoding* standard, but an icon standard. It
standardizes icons -- it doesn't encode them as characters.

There is no clear technical reason to include them.
What *text* problem are you trying to solve by this encoding
that does not already have a solution available?
The scope of the Unicode Standard (and ISO/IEC 10646) does
not extend to encoding every symbol or sign that bears
meaning in the world.
This list has been round and round and round on this -- regular
as clockwork, about once a year, the topic comes up again.
And I see no indication that the UTC or WG2 are any closer
to concluding that bunches of icons should start being included
in the *character* encoding standards simply on the basis
of their being widespread and recognizable icons.
Where is the defensible line between "Fast Forward" and
"Women's Restroom" or "Right Lane Merge Ahead" or
"Danger Crocodiles No Swimming"?
which, of course, has "glyphic" variants:
