Hello -- I am at the start of a font development project. The target font will include some meteorological symbols which were in extensive use in the mid-20th century on teletypewriter networks used to exchange meteorological data around the world. But there is a stumbling block in the assignment of certain glyphs: no apparent Unicode allocation.
At the risk of re-triggering yet another "what is a character" discussion... Have meteorological symbols been considered for incorporation in Unicode? (A search of the archives did not turn up any discussion.) The set of symbols in use has been standardized for many decades by the World Meteorological Organization. The total set is around 150 characters. However, some are already available in Unicode in various locations (arrows, simple thunderstorm symbol, lightning, and other glyphs which can be re-applied in their meteorological context such as various kinds of fog)... and some others can be decomposed in a manner similar to basic letters and diacritical marks. Thanks for your kind assistance. -- Eric Scace
