Our European (and European-descendant) friends seem to use the term "inverted comma" for the mark we call "apostrophe".
I am native born British, having grown up there and spent most of my life there, and I do recall the term inverted comma now that you mention it. However, it is maybe something used around children to avoid them struggling to say (and spell) apostrophe. Apostrophe has always been the formal and correct word, as evidenced by, for example, Keith Waterhouse's AAAA (Association for the Abolition of the Aberrant Apostrophe).
When I was young,the term "inverted commas" was common in Oz,but it was a synonym for "quotation marks"( these things:-
" " ),not apostrophes.
We normally wrote them with the "tails" down like ordinary commas,but I have seen them really "inverted",with the "tail" up,or occasionally with the one at the beginning of the quote "tail down" & the one at the end "tail up".
Back on topic,I think the "rectangular box" resistor symbol significantly pre-dated
computer drafting & was adopted to make it easier for manual drafting.
After all,a rectangular drawing aid was a lot easier to use than a "zigzag line" one.
Another possible reason was the fact that Industrial Electronics liked to draw inductors as zig-zag lines.
These days,computer drafting makes either resistor symbol easy to use,& zigzag lines for inductors never took off in mainstream Electronics.
Australia originally had more influence from the UK & USA than from Europe,hence zigzag resistor symbols became the style of choice.
Japan uses them,too,so another "zig zag" influence was added.
As a result,even though the rectangle style is "supposed to be" the official symbol,both are in wide use.
In the end,both styles are easily readable.
