Using title_separator: "|", page title doesn't display correctly

[billgarrison]

• This is a question about using the theme.
• I believe this to be a bug with the theme --- not Jekyll, GitHub Pages or one of the bundled plugins.
• This is a feature request.
• I have updated all gems with bundle update.
• I have tested locally with bundle exec jekyll build.

Environment informations

• Minimal Mistakes version: 4.1.1
• github-pages or jekyll gem version: Jekyll gem 3.3.1, Ruby 2.4
• Operating system: Mac OS 10.11.6

Expected behavior

Expected to see the "|" character display as a separator in the page breadcrumb path when bookmarking in my browser. What appears instead is a blank space.

Steps to reproduce the behavior

1. In _config.yml, add this line:
   title_separator: "|"
2. run bundle exec jekyll serve and open browser to localhost:4000
3. Attempt to bookmark a page in the browser.
4. Observe that the proposed bookmark title is missing the title separator character of "|".

Interestingly, if I pick a character other than "|" as the title separator, the feature works as expected. E.g.

title_separator: "•" works
title_separator: "&&" works
title_separator: "|" :-(

I haven't tested this yet, but this could be related to YAML. I know you can use | to have it preserve newlines if you do something like:

stats: |
  65 Home Runs
  0.278 Batting Average

Perhaps it's ignoring | when parsing the YAML, which could explain why it's blank. If thats's the case maybe there is a way to escape that character so it shows up. I'd suggest digging into the YAML spec as this appears to be an issue there and not with the theme.

Did some testing and it does seem like YAML or Liquid or Jekyll is removing the vertical pipe |. What you can do instead is declare it as a HTML entity and then it'll work.

title_separator: "|"

Will give you something like:

<title>Welcome to Jekyll | Minimal Mistakes</title>

+1. Thanks! I was going to try an HTML entity next. Thanks for checking this out so quickly.
