Error deploying docs (imcompatible character encodings)

[jakewilliami]

After serve-ing the website locally and it working, I pushed to my GitHub, and it errored:

The tag `asset` on line 24 in `_includes/head.html` is not a recognized Liquid tag.

So then I added a hard constraint on jekyll-assets in the Gemfile as per solution here, but now I am getting this error when trying to deploy:

  Liquid Exception: incompatible character encodings: ASCII-8BIT and UTF-8 in /_layouts/post.html
jekyll 3.8.6 | Error:  incompatible character encodings: ASCII-8BIT and UTF-8

I also had to change line 11 in bin/deploy from

if [ `git branch | grep gh-pages` ]

to

if [[ $(git branch | grep gh-pages) ]]

as it was erroring.

FYI, putting encoding: utf-8 in _config.yml does not fix this issue, nor does changing the line endings.

The file even seems to be a regular file:

$ file -i _layouts/post.html
_layouts/post.html: regular file
