Extra characters on repeated Emojis

[sanzoghenzo]

🐞 Describe the bug

Problem raised in this forum discussion.

Note that this is not strictly related to tables, but with repeated emojis and how the Emojize c# method performs the substitutions.

The regex Match finds all the shorthands, then for each of them it retrieves the icon and performs a replace on the entire text with an html tag with the shorthand as title.
The subsequent match of the same shorthand repeats the replace on the shorthand contained in the title, causing a recursion. that produces extra ">s in the output.

The solution here is to take only the unique/distinct matches of the regex.

As I discussed in the linked topic, it may also be the case to drop the zip archive containing the icons and rely on fonts such as Noto Color Emoji and unicode chars.

I'm already working to address both issues.
