Can`t paste\print Russian symbols into console but cat is working

[Vitaliy]

for example i have the code below

Sys.getlocale()
Sys.setlocale("LC_ALL", locale = "Russian")
A <- 'абвгд'
paste(A, sep = '!')
print(A)

the result of code execution is:

> Sys.getlocale()
[1] "LC_COLLATE=English_United Kingdom.1252;LC_CTYPE=English_United Kingdom.1252;LC_MONETARY=English_United Kingdom.1252;LC_NUMERIC=C;LC_TIME=English_United Kingdom.1252"
Warning message:
In load(path, envir = .GlobalEnv) :
  strings not representable in native encoding will be translated to UTF-8
> Sys.setlocale("LC_ALL", locale = "Russian")
[1] "LC_COLLATE=Russian_Russia.1251;LC_CTYPE=Russian_Russia.1251;LC_MONETARY=Russian_Russia.1251;LC_NUMERIC=C;LC_TIME=Russian_Russia.1251"
> A <- 'АБВГД'
> paste(A, sep = '!')
[1] "\u0410\u0411\u0412\u0413\u0414"
> print(A)
[1] "\u0410\u0411\u0412\u0413\u0414"
> cat(A)
АБВГД

I tried everything what I found in Google, nothing helped to solve this problem .
Also I tried change system locale in: control panel->Region->Administrative->Change system locale->Russian (Russia) and ticked "Beta: Use Unicode UTF-8 for worldwide language support"
Besides I tried to change file encoding into UTF-8 and Global Options->Code->Saving->Default text Encoding UTF-8, Line encoding conversion Platform Native. Into Project Options->Code Editing->Line encoding conversion->Use Default, Text encoding->UTF-8
I really hope for your help.

Try

install.packages("utf8")

Sorry I can't test this, since I don't have a Window box
