Hi,
read.dcf() can modify the locale variable LC_CTYPE, and here is a
minimal example:
> Sys.getlocale('LC_CTYPE')
[1] "en_US.UTF-8"
> read.dcf(textConnection('a: b'), all = TRUE)
a
1 b
> Sys.getlocale('LC_CTYPE')
[1] "C"
After diagnosing the problem, it seems the on.exit() call in
read.dcf() is the culprit:
on.exit(Sys.setlocale("LC_CTYPE", Sys.getlocale("LC_CTYPE")), add = TRUE)
Sys.setlocale("LC_CTYPE", "C")
