It creates this [Why Centmin Mod? ](#why-centmin-mod-) which doesn't work due to the - at the end.

Could it ignore extra spaces at the end?

Thanks for this awesome & easy TOC-creator by the way!

I appreciate your toc generator. As simple as I looked for. I made some small changes fitting my needs. Now I ask if I can publish my changes as you didn't specify a license. I prefer MIT but of course do what is your preference.

Bug description

The markdown

# foo
```
# bar
```

will yield to the following TOC:

- [foo](#foo)
- [bar](#bar)

Expected behaviour:

Ignore # inside code tags. The above markdown should yield to the ToC

- [foo](#foo)

Thanks so much for this online Toc Tool, help me so much :D

I noticed that if only work if there is not accents (é ô è etc) in the title.

When converting my autocue README.md, I realized that underscores _ are removed, resulting in invalid links.

For example, the heading

### Install `cue_file`

gets converted to

  - [Install `cue_file`](#install-cuefile)

instead of

  - [Install `cue_file`](#install-cue_file)

Thanks for a very usable little tool!
