Hi, there are recycling symbols in Unicode (U+2673 to U+2679, RECYCLING SYMBOL FOR TYPE-1 PLASTICS to RECYCLING SYMBOL FOR TYPE-7 PLASTICS). ♳ ♴ ♵ ♶ ♷ ♸ ♹. But currently there are more recycling symbols in use, not only 1 to 7, but also two digits numbers.
How can I find original proposal of including symbols U+2673 to U+2679? I want to simply extend it to new numbers, but use original rationale etc. By the way, can Unicode encode e.g. "combining recycling symbol" (something like U+2672), combined with TWO digits? ---8<--- Piotr Karocki Wszystko co jest poniżej jest samowolnym dopiskiem Google
