Yes. it's a bit of work, but remember, once a character is encoded,
it is forever. That means that it is worthwhile to spend a bit of
time at the start to get it right. Even if that can be a bit
frustrating.<br>

<p>You are part of the way there. You have already collected a nice
set of references that point to these things being defined in
regulations.</p>
<p>In some cases, the version you cite is the original edition from
1994. However, the notes indicate that some revisions took place
in 2018. <br>
</p>
<p>Your task goes beyond collecting a bibliography like this. You
need to cite individual passages, with images as appropriate. If
you can, it would be appropriate to show some examples where these
appear in print, not just embossed in the container. This serves
two purposes: to document that these can be considered "text" and
that there is evidence that the regulation is effective.<br>

<p>Finally, you need to address the issue of what should be encoded
in plain text.</p>
<p>For example, the triangle symbol with an abbreviation below is
potentially not something that should be expressed in plain text.
The main reason would be that the abbreviations are potentially
open ended, so that they are best encoded as text strings. The 2D
placement would then be a matter of a higher level format
protocol.</p>
<p>Something similar applies to multi-digit and other strings
("ABS", "ALU") enclosed in the triangle.</p>
<p>The problem with either approach is that there isn't a generic
protocol which can define 2D layout in such a way that the
resulting shape works like a symbol in text. The big exception
here would be mathematical layout. However, as attractive as that
would seem, it's not really possible to treat the recycling symbol
as a math operator which can take "arguments" like the Summation
or Integral signs.<br>

<p>Something like this would be much preferable over giving some
character code strange behavior in plain text.<br>
<br>

<p>Here is the result of one such search. It appears that the symbol

search. <br>

<p>A proposal that contains detailed research (including relevant

Subject: RE: Recycling symbols
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:
<a class="moz-txt-link-freetext" href="https://www.unicode.org/search/"
moz-do-not-send="true">https://www.unicode.org/search/</a>
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:
<a class="moz-txt-link-freetext"
href="https://util.unicode.org/UnicodeJsps/character.jsp?a=2673&B1=Show"
moz-do-not-send="true">https://util.unicode.org/UnicodeJsps/character.jsp?a=2673&B1=Show</a>
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:
<a class="moz-txt-link-freetext"
href="https://www.unicode.org/versions/enumeratedversions.html"
moz-do-not-send="true">https://www.unicode.org/versions/enumeratedversions.html</a>
There we see that Unicode 3.2 was published in 2002. So, then you can do to
the UTC document registry
<a class="moz-txt-link-freetext" href="https://www.unicode.org/L2/"
moz-do-not-send="true">https://www.unicode.org/L2/</a>
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:
<a class="moz-txt-link-freetext"
href="https://www.unicode.org/L2/L2001/Register-2001.html"
moz-do-not-send="true">https://www.unicode.org/L2/L2001/Register-2001.html</a>
And you'll find the original proposal in 2000:
<a class="moz-txt-link-freetext"
href="https://www.unicode.org/L2/L2000/Register-2000.html"
moz-do-not-send="true">https://www.unicode.org/L2/L2000/Register-2000.html</a>

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?
