Recycling symbols

[Piotr Karocki]

Seems like writing proposal is harder than I thought :)

I just wanted to propose extending list of recycling symbols to meet EU
codes, see e.g.
https://en.wikipedia.org/wiki/Recycling_codes

or, in "more legal act",
https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:31997D0129
(look into PDF file) - table of numbers and abbreviations,
and
https://eur-lex.europa.eu/eli/dir/1994/62/oj/eng, Annex 1:
«The identification marks shall appear in the centre of or below the
graphical marking indicating the reusable or recoverable nature of the
packaging.»

I thing best solution would be only "triangle" with digits, no abbreviation
(it can be added using normal letters). And best of best, as "combining
recycling triangle", if such combining is possible (probably it is not
possible).

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

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?
