Images and emojis in ToC items and headings

[grem11n]

Currently, the code as below produces either ToC item does not match corresonding heading or link not found error depending on whether an image or emoji is included into the Markdown link syntax, i.e. is inside [ ]. Yet, emojis and custom images do not break Markdown links.

Sample code (dots ... correspond to an arbitrary paragraph text).

- ⚙️ [Gear Emoji](#gear-emoji)
- <img src="media/image.png" width="20" height="20" alt="image"/> [Custom Image](#custom-image)

## ⚙️ Gear Emoji
...

## <img src="media/image.png" width="20" height="20" alt="image"/> Custom Image
...

Thus, neither emojis nor custom images are allowed in ToC and headings. Is it done on purpose, or can you otherwise allow emojis in ToC?

Thank you!

It's not done on purpose, but it does have the benefit of not letting people create messy readme's with lots of unnecessary emojis.

Although, some emojis can make a list a bit prettier I totally understand that it can easily go out of hand. Thank you for the explanation!
