I think this is a "feature" of win_iconv that is bundled with base R on Windows (./src/extra/win_iconv). The character from your example is not part of the latin1 (iso-8859-1) set, however, win-iconv seems to do so anyway: > x <- "\U00159" > print(x) [1] "ř" > iconv(x, 'UTF-8', 'iso-8859-1') [1] "r" On MacOS, iconv tells us this character cannot be represented as latin1: > x <- "\U00159" > print(x) [1] "ř" > iconv(x, 'UTF-8', 'iso-8859-1') [1] NA I'm actually not sure why base-R needs win_iconv (but I'm not an encoding expert at all). Perhaps we could try to unbundle it and use the standard libiconv provided by the Rtools toolchain bundle to get more consistent results. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
