This problem has existed for years. I know this is not a trivial fix, but its really a pain to work with foreign text in R under windows. ***This is a Windows only problem***. R will typically read foreing characters correctly, but it will not display them in the output. This problem exists regardless of file format, language, structure etc. If the character is foreign, the best R can do is show the UTF-encoding. The problem has been widely observed and documented over the years.

stndard code to reproduce the problem:

raw_table1 <- read.csv("UTF8_nobom_cyrillic.csv", header = FALSE, sep = ",", quote = "\"", dec = ".", fill = TRUE, comment.char = "", encoding = "UTF-8")

In the best case scenario youll get somethibg like this:

Is there any hope that R on Windows will ever fully support foreign text?
