I have removed these characters on a fork and works fine (except that doesn't build now because cran is down, but locally is perfect). That was not picked on the PR that introduced these changes because it seems that the actions running on the PR doesn't try to build the site.
I don't know how to contribute these changes, as that happens when the code is run via literate.
In the last commit, there is a set of ANSI characters from precompiling the packages. This made the website to stop building the latest version.
