问题
I want to execute a system command from gvim and retrieve the output of that command in the current buffer. So i run the following command in gvim:
:r echo éèà
However the result shows three black squares instead of the echoed characters. I have not yet figure out what to do to get this to work. I have the following encoding setup:
set encoding=utf8
set termencoding=cp850
My windows console encoding is cp850.

TL;DR
:r! echo éèà | c:\cygwin\bin\iconv -f cp850 -t cp1252
Assumptions
I have been able to reproduce your problem on my Windows 10 machine using gvim 7.4, installed via the Windows installer for gvim.
I also have cygwin on my machine, in which I have iconv, and its full path is c:\gygwin\bin\iconv.
Proposed solution
Apparently, gvim expects the output from the Windows shell to be in cp1252 because this worked for me:
:r! echo éèà | c:\cygwin\bin\iconv -f cp850 -t cp1252
I checked the results, and Vim correctly inserted the utf-8 characters for éèà in my document.
I don't have an equivalent to iconv that is Windows native, but if you have Cygwin you can add c:\cygwin\bin to your Windows path and the command should not require an explicit path.
Epilogue
Yuck. This is ugly. The solution works, at least on my machine, but I hope someone finds and posts a more elegant solution.
There ought to be a way to tell gvim what encoding to expect from the shell, but I did not find it. I played with various combinations of settings of encoding, termencoding and fileencoding instead of using iconv, but only managed to get different wrong results.
These related questions faced similar problems but their solutions didn't work in my tests either:

- https://vi.stackexchange.com/questions/7105/wrong-encoding-while-calling-shell
The problem stems from the mismatch in character encoding between cmd.exe (default :set shell in vim on Windows) and what gvim expects. I don't know why changing :set termencoding does not fix the problem.
