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?
