Encoding bug?

[giuseppec]

There seem to be an encoding issue at least for windows (not sure if this is because of windows java or windows or farff):

    oml.conf = getOMLConfig()
    cachedir = oml.conf$cachedir
    data.id = 376
    data.reader = "readr"
    getOMLDataSet(data.id)
    path = file.path(cachedir, "datasets", data.id, "dataset.arff")
    d1 = readARFF(path, data.reader = data.reader)
    d2 = RWeka::read.arff(path)
    for(i in 1:nrow(d1)){ 
      cat(i, fill = TRUE)
      expect_equal(d1$text[i], d2$text[i])
    }
    expect_equal(d1$text[7], d2$text[7])
    d1$text[7]
    d2$text[7]

the first string mismatch happens in row 7 of this data set and refers to the string ¤, which in RWeka is represented as ¤. I have experimented with the iconv function to convert the character into UTF-8 but it did not work. Does this work for other operating systems?

does not work

No problems on OS X with this code.

isnt this basically a readr issue?
what happens if you parse a file with a similar example plainly in readr?

@giuseppec
can you try to set the local parameter in read_delim, to specify an encoding on our windows system?
does this help?
