How to generate TOC with special chars in .md file?

[astraw99]

In my .md file, want to add TOC of all the titles and subtitles, like below:

TOC
- [1. Docker ENTRYPOINT vs CMD](#1-Docker-ENTRYPOINT-vs-CMD)
    - [1.1 Only ENTRYPOINT](#11-Only-ENTRYPOINT)
    - [1.2 Both ENTRYPOINT + CMD](#12-Both-ENTRYPOINT---CMD)

In the link part, the space char is replaced with '-', but how to replace the '+' char?
Tried with '---' to replace '+', but it didn't work. Anyone help?

If you hover the mouse over the link symbol that appears if your mouse is over a heading, your browser should show you the direct link. Look at the anchor part of that to figure out the anchor you need to use, that works for any characters.

I mean the symbol on the left:
