Might it be possible to tweak the current configuration settings around Markdown typographer (also known as “smart punctuation”) to enable Unicode punctuation marks, like quotation marks and dashes, but disable (c), ™, and potentially other specialized glyphs of the kind?
I’m a lawyer. I advise on trademarks and copyrights all the time, including on Discourse forums. I have yet to advise anyone to revise a post to add a copyright or trademark symbol, and non-lawyers tend to massively overestimate how often they’re useful or necessary. On the flip side, I’ve edited more posts than I can count to try and trick the Markdown rendered into not rendering the © symbol.
This comes up especially often in enumerated lists. For example:
This enumeration style is very common in laws, contracts, policies, and other formal writing influenced by legal style. It’s also a very common outline style. It was part of the “standard” outline style I was taught as a grade school student in the United States.
I see the current settings offer some flexibility around the punctuation, but not, as far as I can tell, any way to enable smart punctuation without enabling smart symbols.
