Read or write files, assuming they are encoded in UTF-8. read_utf8()
is roughly readLines(encoding = 'UTF-8') (a warning will be issued if
non-UTF8 lines are found), and write_utf8() calls
writeLines(enc2utf8(text), useBytes = TRUE).
read_utf8(con, error = FALSE)write_utf8(text, con, ...)
A connection or a file path.
Whether to signal an error when non-UTF8 characters are detected
(if FALSE, only a warning message is issued).
A character vector (will be converted to UTF-8 via
enc2utf8()).
Other arguments passed to writeLines() (except
useBytes, which is TRUE in write_utf8()).
