Please add an option for accessible footnotes

[borisschapira]

In the html_renderer.rb, please add an aria-label attribute to the footnote "↩" backlink with a default "Back to content" value.
In a second time, allow this value to be modified by a configuration so that developers at the end of the chain could configure a localized value depending on the content locale.

Hi there, thank you for opening an issue. Since this would be an addition to the formal Commonmark spec, I suggest opening it over where the development of that spec occurs: https://github.com/github/cmark-gfm

The intent of this repository is to just prove a single Ruby wrapper for the existing C code. It does not add any features that do not already exist in github/cmark-gfm.

Alternative, you are free to create your own custom renderer as a plugin/add-on: https://github.com/gjtorikian/commonmarker#creating-a-custom-renderer. For example, you can see how commonmarker-rouge added syntac highlighting to code blocks on top of this gem.

Ah, my apologies, I did a quick re-read and the autoreply there isn't entirely accurate. The aria-label generation issue would still need to be opened at https://github.com/github/cmark-gfm (but this isn't technically a new addition to the spec, I don't think?).

Sorry to have bothered you. I saw that the code came from a renderer defined in this project, so I opened an issue here. The Custom Renderer may be a solution, I'll propose it to jekyll-commonmark. As I don't see any renderer in cmark-gfm, I wonder how it could be handled there.
