Markdown beautifying shots

This is a playground for attempts at improving Markdown before display for the user. Current implementation only supports French rules.

Here are some examples of objectives:

• Replace <space>? with <nbsp;>? (in French, a question mark is preceeded with a space, but you don't want the line to break). And similar for other punctuations as needed.

  Eg Showdown est super ! would be converted as Showdown est super !

• Add thousand separators in numbers.

  Eg 1234567 would be converted as 1,234,567 (or narrow no-break space as thousand separator in French).

Of course we want to do that only in text. We don't want to alter citations or hyperlinks.

The file of interest is index.js. You probably don't want to compile the project; but in case you want to, just open the sln file with Visual Studio (I use version 2022).
