Proper table printing broken with R 3.5

[beansrowning]

Setup:

• R 3.5.0
• rtichoke 0.1.2
• Windows 10
• ConEmu

Reproducible example:

data.frame(a = 1:2, x = c("a", "b"))
#> ☻ÿþa♥ÿþ ☻ÿþx♥ÿþ
#> ☻ÿþ1♥ÿþ ☻ÿþ1♥ÿþ ☻ÿþa♥ÿþ
#> ☻ÿþ2♥ÿþ ☻ÿþ2♥ÿþ ☻ÿþb♥ÿþ

For the record, it works fine on macOS.

Data.table looks to be affected too:

data.table(a = 1:2, x = c("a", "b"))
#>  ☻ÿþa♥ÿþ ☻ÿþx♥ÿþ
#>☻ÿþ1:♥ÿþ ☻ÿþ1♥ÿþ ☻ÿþa♥ÿþ
#>☻ÿþ2:♥ÿþ ☻ÿþ2♥ÿþ ☻ÿþb♥ÿþ

Not tibbles though:

tibble(a = 1:2, x = c("a", "b"))
#> # A tibble: 2 x 2
#>       a x
#>   <int> <chr>
#>  1     1 a
#>  2     2 b

It works fine both on Cmder and Command Prompt.

It looks like your R version is 3.4.3. Here's what I'm getting with 3.5:

[randy3k]

I assume that it works as expected in regular R, right?
TBH, I have no clues why it happens.

PS: I just installed Conemu, it also works as usual.

[randy3k]

Oh, yeah. I can reproduce it with R 3.5.

r$> "hello"
[1] "☻ÿþhello♥ÿþ"

[beansrowning]

Yeah regular R works fine--I'm using cmder as well FWIW.

I dug around a bit in the R repo and didn't see any major changes to printing, nor was there anything in the release notes. Very odd.

[randy3k]

More odd,

r$> list(a = 1, b = 2)
$`☻ÿþa♥ÿþ`
[1] 1

$b
[1] 2

[randy3k]

for reason which i don't understand, "a" is printed as "\x02\xff\xfea\x03\xff\xfe" with the extra escaped characters.

[beansrowning]

That is just odd...what has changed do you think?

[randy3k]

I notice that rstudio has code related to these escaped characters.

[beansrowning]

The relevant commit from Joe Cheng, if you didn't see that already. Looks like R output needs to be homogenized to utf-8.

Still doesn't really explain why 3.5 should be different, but there you are.

[randy3k]

4e29747 should fix it.

I don't know if this helps, but 0xFEFF is the UTF-16 encoding of the byte order mark.

@randy3k Confirmed working on Command Prompt and Cmder with the most recent version. Nice work!

[randy3k]

But I still don’t understand what happens to R 3.5 is causing this.
