Broken autolink when - (dash) used in the title

[ig-vb]

Autolinking generates wrong TOC when dash (- ) used in the title.

How can the issue be reproduced

# One title

# Second - title

What was expected

<!-- MarkdownTOC autolink="true" -->

- [One title](#one-title)
- [Second - title](#second-title)

<!-- /MarkdownTOC -->

What actually occurred

<!-- MarkdownTOC autolink="true" -->

- [One title](#one-title)
- [Second - title](#second---title)

<!-- /MarkdownTOC -->

What was the version of the involved component

MarkdownTOC v3.0.5 and Sublime 3.2.2 build 3211

Hi @ig-vb

What does the anchored ID look like? does it match the generated autolink with the consecutive dashes:

<a id="#second---title"></a>

or is it different?

Do the links work even though they do not resemble the titles exactly.

Hi @jonasbn

The generated autolink is:

- [Second - title](#second---title)

but the anchored ID is different.

This title:

Second - title

will get this anchor:

#second-title

So the links do not work. Correct, working link, generated by the plugin should be:

- [Second - title](#second-title)

Hello, everybody.

I can't reproduce the issue reported here, neither in MarkdownTOC 3.0.4 nor in the recently updated to 3.0.5. The generated markup with the example given is:

<!-- MarkdownTOC autolink="true" -->

- [One title](#one-title)
- [Second - title](#second---title)

<!-- /MarkdownTOC -->

<a id="one-title"></a>
# One title

<a id="second---title"></a>
# Second - title

The ID second---title is a valid ID and it's functional.

After further testing, the generated links work with GitHub, but they are not working in GitLab.

It seems that the plugin is working correctly, the problem seems to be at GitLab. Please close this issue if you agree.

Hi, you can deal with this by:

{
  "id_replacements": [
    {
      "pattern": "\\s+",
      "replacement": "-"
    }
  ]
}

↓

{
  "id_replacements": [
    {
      "pattern": "\\s+",
      "replacement": ""
    }
  ]
}

on your user settings (MarkdownTOC.sublime-setting).
