  • Helpers read_lines and write_lines do the right thing
  • readLines() and writeLines() through errors to prevent accidental re-use in the future
  • Warn if package encoding is not utf-8

Fixes #564. Fixes #592

Fails on windows: https://builder.r-hub.io/status/roxygen2_6.0.1.9000.tar.gz-0fb096cb600844e7ae02dfc17e57c101

@krlmlr do you happen to remember why the useBytes = TRUE in writeLines(contents, path, useBytes = TRUE) is necessary for windows?

@hadley otherwise the text is re-encoded to the native encoding. I think it is necessary on all platforms that are not utf-8 and not byte-oriented.

I have code for reading UTF-8 files in my dep-free utf8 package, which I'll release very soon.

@gaborcsardi even though I'm writing to a utf-8 connection??!

Yes, R does an involuntary roundtrip via the native encoding.

Still fails on windows with useBytes. I'll diagnose in my windows VM.

Update DESCRIPTION: add encoding to meet roxygen2 >= v6.1.0
44efb8b 
- since r-lib/roxygen2#649 (`roxygen2` >= v6.1.0) warns if a `DESCRIPTION` file does not explicitly define its encoding as UTF-8
- this commits adds encoding information to the DESCRIPTION file even if it may be at odds with `Writing R Extensions` (https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Encoding-issues), but see r-lib/roxygen2#774

- at least, this works for me locally and eliminates the `roxygen2` warning "roxygen2 requires Encoding: UTF-8"
