R devel - May 2015 - Unicode display problem with data frames under Windows

Here's a data frame with some Unicode symbols (set intersection and union).

d <- data.frame(x = "A \u222a B \u2229 C")

Printing this data frame under R 3.2.0 patched (r68378) and Windows 7, I see

d
##                  x
## 1 A <U+222A> B n C

Printing the column itself works fine.

d$x
## [1] A ? B ? C
## Levels: A ? B ? C

The encoding is correctly UTF-8.

Encoding(as.character(d$x))
## [1] "UTF-8"

Under Linux both forms of printing are fine for me.

I'm not quite sure whether I've missed a setting or if this is a bug, so

Am I doing something silly?
Can anyone else reproduce this?

AFAIK this is the way it works on Windows. It has been discussed in several
places, e.g.

,

(both of these came up when I googled the subject line of your email).

Yes, but it is a bug, just a hard one to fix.  It needs someone to 
dedicate a serious amount of time to deal with it.

Since most of the people who tend to do that generally use systems in 
UTF-8 locales where this isn't a problem, or don't use Windows, it is 
languishing.
