Your description looks more like a glyph specification than a (more 
semantic) character description. I suspect that ⏴U+23F4 BLACK MEDIUM 
LEFT-POINTING TRIANGLE and ⏵U+23F5 BLACK MEDIUM RIGHT-POINTING TRIANGLE, 
introduced in Unicode 7.0 as interface symbols (anyone remember which 
proposal it was ?) are what you are looking for.

This one seems legit to me, but the “external link sign” seemed legit to 
me and was rejected (see http://unicode.org/alloc/nonapprovals.html ).

You are looking for ⏸U+23F8 DOUBLE VERTICAL BAR (alternate name: pause), 
introduced in Unicode 7.0 for that specific purpose (I don’t remember 
the proposal)

As said by Steven, this one is already in the pipeline, even if not 
accepted yet

Things like �� U+1F512 LOCK ?

That is not a Unicode problem, it is an interface problem, arguably a 
bug in CLI/console developement.

The shopping cart is currently under consideration (see 
http://www.unicode.org/L2/L2015/15195r2-emoji-add-tranche6.pdf, as U+1F6D2)

That’s a big No since 1999 : these symbols are logos, and excluded with 
Unicode. No one wants to deal with the legal nightmares of doing so.
