Thank you, now I understand a little more.
My real problem, however is a data frame produced
by spss.get(). Is there a simple possibility to
mark all characters in that data.frame (except
ASCII characters), including levels of factors to latin1?
Heinz Tüchler
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"
