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 ©, ™, 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.
