Error in yaml.load: control characters are not allowed

Error in yaml.load(string, error.label = error.label, ...) : 
  Reader error: control characters are not allowed: #83 at 12

This error comes with special characters in your dev_history.Rmd YAML. This is corrected with development version of {parsermd} (parsermd >= 0.1.2.9000) : remotes::install_github("rundel/parsermd").
If you do not want to use the development version of {parsermd}, remove special characters from your YAML.
