Thank you for the report and initial debugging. I am not sure what is going wrong, we may have to rely on your help to debug this (I do not have a system to reproduce on). A user-targeted advice would be to use RGui (Rgui.exe).
Does the problem also exist in R-devel? https://cran.r-project.org/bin/windows/base/rdevel.html Your example print("ABC\u4f60\u597dDEF") is printing two Chinese characters, right? The first one is C4E3 in CP936 (4F60 in Unicode) and the second one is BAC3 in CP936 (597D in Unicode)? Could you reproduce the problem with printing just one of the characters, say print("ABC\u4f60DEF") ? As a sanity check - does this display the correct characters in RGui? It should, and does on my system, as RGui uses Unicode internally. By correct I mean the characters shown e.g. here https://msdn.microsoft.com/en-us/library/cc194923.aspx https://msdn.microsoft.com/en-us/library/cc194920.aspx What is the output of "chcp" in the terminal, before you run R.exe? It may be different from what Sys.getlocale() gives in R. If you take the sequence of the "fputc" commands you captured by the debugger, and create a trivial console application to just run them - would the characters display correctly in the same terminal from which you run R.exe?
