How to use unicode in string literals

Question

I know that I can use the \U prefix to encode unicode characters:

cat("\U00DF", "\n")
# ß

But how would I use it in a longer string?

cat("Stra\U00DFe", "\n")
# Stra෾

Do I really need to paste strings along the unicode "breaking points"?

cat(paste0("Stra", "\U00DF", "e"), "\n")
# Straße

I guess I do not see the wood for the trees, so any hint is highly appreciated?

Answer 1

You could {} of your unicode like this:

cat("Stra\U{00DF}e", "\n")
#> Straße
