Heading Icon causing confusion in editor

[thewebprincess]

Is your feature request related to a problem? Please describe.
I find the use of the bookmark icon to denote the heading to be super confusing. I had cause to want to change an errant heading back to a paragraph and almost had to google how to do it because this icon does not say heading to me, it says 'save' or 'bookmark' - It wasn't until I looked at another block and noted the pilcrow denoting the paragraph block that I realised my mistake.

Describe alternatives you've considered
It seems to me than in every other instance in which we're talking about headings they're denoted with a capital H While I realise this is specific to English - it is also specific to HTML I feel like there ought to be a way to do it without co-opting an icon that is commonly used in other contexts and therefore causes confusion when being used in this way.

This was also mentioned in #24168.

Good point. I tried to put together a few ideas - there aren't a lot of icons out there that scream "heading"! I tried two from Material that kind of evoke the semantic hierarchy, but maybe in the end 'H' is still the clearest.
I wasn't a super big fan at first, since as you said: it's an english letter, but it's true that the HTML spec uses H1-H2-H3 etc explicitly, as do we in the UI already to specify the heading level actually, so it should be fine. Inspired by this icon I also tried a variation of the H to indicate the levels a little more.

Thanks @hedgefield -Reinventing the wheel and making users have to think about what they're trying to do instead of just getting on with it is alienating. While creating a new icon to represent a heading in something like WordPress given its marketshare could in fact eventually usher in a new default (much the same as the bookmark/save icon has become), I strongly suggest sticking with the status quo. Using an H has become synonymous in other apps (Notion for example) and either of your options related to that would, from my perspective, reduce the ambiguity I was frustrated by. Thank you.

[hedgefield]

I agree. I think the H is pretty commonplace and safe to pick, let's go with that then :) @noisysocks can you tell us what is needed to carry out this icon replacement? Do you think it's possibly to get it in before 9.9?

Adding in some older and closed Heading discussion issues/PR:
#522
#9159

Joen @jasmussen will likely have some comments on this issue.

Hmm I am not able to find an issue from 2-3 years back where I added a lot of different Heading icons.

[jasmussen]

Thanks for the ticket. "H" is for "Heading", which works well for english, but is meaningless outside english speaking countries, and as Paal notes, we also tried it in the past. The bookmark harkens back to the table of contents usage of headings as anchors across a web-page.

The feedback is valid, and if we find a better design than the bookmark, I'd be happy to change it.

So as to consolidate things, though, I'm going to close this one in favor of #24168. I'll label both with "Icons" so they don't disappear.
