Meteorological symbols for cloud conditions (on maps or elsewhere)

See
https://fr.wikipedia.org/wiki/Carte_m%C3%A9t%C3%A9orologique#/media/File:Station_model_fr.svg

I see these symbols for noting cloud types (here cirrus and altocumulus,
one drawn in diagonal for middle altitude, another drawn horizontally for
high altitudes).

Note that the symbols may vary: see Altocumulus for example as found in
French Wikipedia (note sure if it's accurate) which is different from the
symbol found in the sampled notation on a map

https://fr.wikipedia.org/wiki/Altocumulus

Also other symbols on the similar page in English Wikipedia, are used to
describe some cloud characteristics:

Is there a well defined collection of these symbols, and are they in the
encoding pipe ?
