R devel's bind.c has been ported to R patched. Is it OK while names of 'unlist' or 'c' result may be not strictly the same as in R 3.4.1 because of changed function 'NewName' in bind.c?

Using 'translateCharUTF8' instead of 'translateChar' is as it should be. It has an effect in non-UTF-8 locale for this example.
x <- list(1:2)
names(x) <- "\ue7"
res <- unlist(x)
charToRaw(names(res)[1])

Directly assigning 'tag' to 'ans' is more efficient, but may be different from in R 3.4.1 that involves 'translateCharUTF8', that is also correct. It has an effect for this example.
x <- 0
names(x) <- "\xe7"
Encoding(names(x)) <- "latin1"
res <- c(x)
Encoding(names(res))
charToRaw(names(res))
