I don't know the cause or a fix, but a way to avoid the error would be 
to make the example conditional on not being on Solaris.  I would guess 
this test would do it:

if (!grepl("solaris", R.version$platform)) {
     emoji.txt.gz <- system.file("extdata", 
"wikipedia-emoji-text.txt.gz", package="nc")
     ETC.

I'd add a comment explaining why you have this test...
