Table of content not referring unicode characters

Question

I have the following title:

##A Title with icon ✏

I want to reference it in a table of contents but the following does not work:

- [A Title with icon ✏](#a-title-with-icon-✏)

It is also fine to remove the icon in the summary, but how to accomplish the linking?

Answer 1

To link the following title (pay attention to space after hashes):

## A Title with icon ✏

just ignore the Unicode character (pay attention to the trailing hyphen):

- [A Title with icon ✏](#a-title-with-icon-)

P.S: tested on GitHub and BitBucket, it works fine.
