I suppose it's very simple but I can't find the way to generate a sequence of

Could you please help me with this?
If you want the standard collation sequence, use the letters variable,
as others have said.
If you want the sequence that applies in your locale (where does "ü"
fall?), it's harder. I don't know a simple way, but this gives you
collation order in the German locale in Windows:
> x <- as.raw(32:255)
> y <- readChar(x, rep(1, 224))
> Sys.setlocale("LC_COLLATE", "German")
[1] "German_Germany.1252"
