Regression with v14.1.0 regarding ~~strikethrough text~~

[Lucas-C]

Hi

Thank you for maintining markdown-it!

I discovered a minor regression with the latest published version:

$ node -v
v18.19.1

$ npm i markdown-it@14.0.0

$ node -e 'console.log(require("markdown-it")().render("~~⚀~~one"))'
<p><s>⚀</s>one</p>

$ npm i markdown-it@14.1.0

$ node -e 'console.log(require("markdown-it")().render("~~⚀~~one"))'
<p>~~⚀~~one</p>

This bug only appears when using non-ASCII characters: it won't happen if ⚀ is replaced by 1 in the sample code above.

This is so much easier to test different versions with:

$ echo "import md from 'npm:markdown-it@14.0.0'; console.log(md().render('~~⚀~~one'));" | deno run -
<p><s>⚀</s>one</p>
$ echo "import md from 'npm:markdown-it@14.1.0'; console.log(md().render('~~⚀~~one'));" | deno run -
<p>~~⚀~~one</p>

Thanks for the report. But I think that it is not a bug, but intentional change in the spec: #1009 (see point 3)

⚀ is Other Symbol (So), and the entire S class is now treated as punctuation which it wasn't before (so now behavior is the same as with ~~&~~one for example).
