Not per se. And yes, this will trigger another "what is a character"
discussion, I fear.

Can you point us to a specific document? http://www.wmo.ch lists
hundreds of publications, but nothing that I could see or search
for easily that points to a standard for meteorological symbols.
Also, you need to take into account that whatever the WMO may
state about this in a standard document may or may not reflect
computer practice reflected in fonts, other character encodings,
and actual practice around the world.

Unless the WMO has promulgated a *character* encoding standard
that we don't know about, the fact that there is a standard
list of some 150 images for symbols begs the question whether
these are characters or not. ISO has *many* standards for symbols
and icons of various sorts. They clearly do not all constitute

Point the UTC to the set of 150 things standardized by the WMO,
and let the debate begin.
