When revisiting the icons I've stumbled upon the 'quotes' RTL treatment in T177432, which was taken over from icon design before the refresh.
These seem false from directionality and axis orientation, see https://en.wikipedia.org/wiki/Quotation_mark#Summary_table shared by Ed below.
Tried to find appropriate comparisons on Hebrew and Farsi pages, but even better reaching out to native speakers. :)
In-text treatment: Straight quotes " or mirrored vertically.
In-text treatment «»
- Amend quotes to language-specific quotes
- Pro: Provide typographically, non-US-English-centric quote icon, pleasing other language speakers
- Possible con: quotes is not inserting quotes, it's pointing to “Cite” functionality in VE's main toolbar, and once to “whole words” functionality in VE's Find and replace dialog. So it's an abstraction that should probably see an abstracted icon itself
- Amend quotes to language-neutral icon.
