Hello
When I read a SPSS *.por file with read.spss everything after a umlaut is
missing:
This sounds like a conflict between encodings -- eg if R is assuming UTF-8
and the file is encoding in Latin-1 then the sequence
U+00FC : LATIN SMALL LETTER U WITH DIAERESIS
U+0072 : LATIN SMALL LETTER R
is coded as FC72 in the file, which is an illegal byte sequence in UTF-8.
The underlying C code (being written in the US quite a long time ago)
doesn't know about encodings, and I don't know what the rules are in SPSS
for valid characters (I suspect that in these old portable file formats it
probably just reads and writes bytes, leaving it up to the OS to interpret
them.
You could try running R in a non-UTF-8 locale to see if it helps.
If anyone has definitive information about how SPSS represents strings and
decides on valid characters that might be useful too.
