See the 'R Internals' manual.
ASCII characters are not marked as Latin-1 nor UTF-8.

Dear All,
Encoding() goes beyond my understanding. See the example. I would expect from
reading the help for Encoding() that strsplit preserves the encoding for each
resulting element, but for simple letters it gets lost.
Also it seems that an Encoding() cannot be declared for simple letters. They
remain in any case "unknown". In paste() "latin1" seems to dominate
"unknown".
What kind of characteristic of an object is the encoding? It does not show up
as attribute and also str() does not give me any hint.
Where can I find some explanation regarding encoding?
Thanks
Heinz
### Encoding() and strsplit
u <- 'abcäöü'
Encoding(u)
[1] "latin1"
Encoding(u) <- 'latin1' # to be sure about encoding
us <- strsplit(u, '')[[1]] # split in single strings
Encoding(us)
[1] "unknown" "unknown" "unknown" "latin1" "latin1" "latin1"
Encoding(us) <- rep('latin1', length(us))
Encoding(us)
[1] "unknown" "unknown" "unknown" "latin1" "latin1" "latin1"
pus <- paste(us[1], us[5], sep='')
Encoding(pus)
[1] "latin1"
