Hi, I'm running the actual R version in JGR (version 1.5-8 ). Sys.getlocale(category = "LC_ALL") yields [1] "LC_COLLATE=German_Germany.1252;LC_CTYPE=German_Germany.1252;LC_MONETARY=German_Germany.1252;LC_NUMERIC=C;LC_TIME=German_Germany.1252" I want to write some HTML-Code enhanced by statistical results and labels encoded in Latin-1, which I pass to a function. Some label shall generate the filename. Although the labels are correctly handled in JGR they are somehow converted when they are written to the file. Also the filename is not constructed as wanted. The function definition is correctly sourced into R. The function is defined like this: Itemtabelle.head <- function (abt ){ # n?r z?m T?ST abt = iconv(abt,"UTF-8","LATIN1") zz = file( paste("Itemtabelle/Itemtabelle", abt, ".html"), "wt", encoding = "LATIN1") cat(as.character("<html xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> \n"), as.character(" <head> \n"), . . . as.character(" <td colspan=5 class=xl28 width=727 style=\'width:545pt\'>Gesundheitsindikatoren: "), abt, as.character("</td> \n"), as.character(" </tr> "), file = zz) close(zz) unlink(zz) } Setting abt as " ?rzte Innere, Gyn?kologie" and calling the function with this argument, yields a filename "Itemtabelle ??rzte Innere, Gyn??kologie .html" and in the file a line <td colspan=5 class=xl28 width=727 style='width:545pt'>Gesundheitsindikatoren: ????rzte Innere, Gyn????kologie </td> is generated. . The problem remains the same in the rgui and rterm - except in rterm the resulting filename is "Itemtabelle ?rzte Innere, Gyn?kologie .html". Cheers, Matthias
