R 3.5 - read.csv not able to read UTF-16 csv file

问题

My code is as follows:

read.csv("http://asic.gov.au/Reports/YTD/2018/RR20180420-001-SSDailyYTD.csv", skip=1, fileEncoding = "UTF-16", sep = "\t", header = FALSE)

R 3.4.3 - Code executes cleanly
R 3.5.0 - gives the following error:

Error in read.table(file = file, header = header, sep = sep, quote = quote, : no lines available in input

@hrbrmstr - session info readout

Is this a bug in the new R version or
Am I missing something

Please help me!

I received errors as well. This, however, works:

csv_url <- "http://asic.gov.au/Reports/YTD/2018/RR20180420-001-SSDailyYTD.csv"

download.file(csv_url, basename(csv_url))

read.csv(
  basename(csv_url), skip = 1, fileEncoding = "UTF-16", sep = "\t", header = FALSE
)

If you do not have an account on https://bugs.r-project.org/bugzilla/ or it won't let you make one, let me know and I'll file a bug report for you after testing on a linux system (I'm on macOS and if you could add the output of sessionInfo() to your question that'd be 👍)

I will note that even readr::read_tsv() has issues with this file so there may be legitimate encoding issues that older R versions were less stringent about.
