If you want to find a proposal for a character, one thing you can do is use search. For example, try searching for "recycling" using one of the search options on this page:
https://www.unicode.org/search/ Another thing you can do is to determine the age of the character (what version it was added in) — you can see that for 2673 using the character properties utility: https://util.unicode.org/UnicodeJsps/character.jsp?a=2673&B1=Show That shows that U+2673 was added in Unicode 3.2. Then you can go to this page to find out what year that version was published: https://www.unicode.org/versions/enumeratedversions.html There we see that Unicode 3.2 was published in 2002. So, then you can do to the UTC document registry https://www.unicode.org/L2/ and start searching in the index pages from 2002 and earlier. Doing that, you'll find three documents with "recycling" in their titles in 2001 that are all discussing the characters in process of being encoded: https://www.unicode.org/L2/L2001/Register-2001.html And you'll find the original proposal in 2000: https://www.unicode.org/L2/L2000/Register-2000.html Peter -----Original Message----- From: Unicode <unicode-boun...@corp.unicode.org> On Behalf Of Piotr Karocki via Unicode Sent: April 18, 2025 12:48 PM To: unicode@corp.unicode.org Subject: Recycling symbols 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
