I think I might be running into a bug related to this. Here's a reprex: ``` r library(tidyverse) mod % ciTools::add_pi(mod) #> Error in model.frame.default(formula = mpg ~ disp, data...

I think this issue is in [ropensci/crul client.R:526](https://github.com/ropensci/crul/blob/967b19f7552afe7703a05aba395ca48ef0398dd6/R/client.R#L526). `crul` doesn't seem to handle non-UTF-8 response headers. I'm running into the same issue with DOI:10.1126/science.aax9044.

@schiavone1 I don't think there's a workaround possible from the `rcrossref` side. I made a [pull request](https://github.com/ropensci/crul/pull/164) to fix the underlying issue in `crul`. You might try installing my version...

Seconded! This would help my research, too.
