There is more support for installing UTF-8-encoded packages in a strict Latin-1 locale (and probably for other Latin locales): non-ASCII comments in R code are worked around better.
‘reformulate("x", response = "sin(y)")’ no longer produces extra back quotes, PR#17359, and gains new optional argument ‘env’.
