To reproduce:

1. Run git clone [email protected]:lem-project/lem-project.github.io.git
2. Reset the HEAD to d5e3548aef9eadf2ed36fb274c4105a9344b39e6.
3. Open the project using lem.
4. Run lem/grep::project-grep with arg git grep -niHi 'grep'.
5. Get the error.

It seems like the big js file causing the error, or some problems about the string escape.

Another interesting command: Run lem/grep::project-gre with git grep -nHI 'webpack'.
And the lem will crash directly without any error message.

To reproduce:

1. Run `git clone [email protected]:lem-project/lem-project.github.io.git`

2. Reset the `HEAD` to `d5e3548aef9eadf2ed36fb274c4105a9344b39e6`.

3. Open the project using `lem`.

4. Run `lem/grep::project-grep` with arg `git grep -niHi 'grep'`.

5. Get the error.

This should be fix by #1741.

I believe this is because Lem cannot handle so many super long lines.

I get this error when I attempt to open the dashboard, maybe because of the <U+E908> <U+F0C9> and <U+F011> characters (Edit: the characters display if visit the file so they don't appear to be the problem). Is this different than the issue reported here and the one meant to be fixed by #1741? The error is displayed and the dashboard is not.
