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: https://en.wikipedia.org/wiki/Altocumulus_cloud Is there a well defined collection of these symbols, and are they in the encoding pipe ?
