Considering UTF-8 + Windows CMD nightmare...
After reading this question, are these solutions only partial ? Is there a way to set globally the character set/encoding in a cmd environment? It seems that CHCP command does not change the stdout/stderr encodings.
To check it: write a program that fills a file with latin/korean/ukrainian strings.
On direct output, the file will be ok if you set the encoding properly into your source code (i checked it with Java, easy encoding settings for files).
But if you redirect your output into a log file, you will simply have series of ???????????????????? in it ...
The indirection could be useful too, like this:
PROMPT> myprog < inputdata.txt > outputdata.txt
Am i missing something? Is it cmd that badly converts stdout, or Java that adapts System.out, depending of the cmd encoding? I have not found any method to re-define System.out/err encoding.

Read http://ss64.com/nt/chcp.html and this detailed analysis in great answer by @andrewdotn to another question at SO. FYI, I have
– JosefZ – 2015-06-17T15:58:01.480DejaVu Sans Monofont installed.To answer the question of whether it's cmd or the program.. try pasting the character into cmd, if it goes there then cmd is fine. i.e. the font supports it. I find type can display a file with funny characters if it's unicode LE(xxd -p file, look for fffe at the start, save file in notepad as 'unicode' that's unicode little endian), but more cannot display these funny characters. – barlop – 2015-06-17T23:49:26.407
a related question but for C# http://stackoverflow.com/questions/30904504/font-is-right-why-cant-i-get-this-unicode-character-to-display-in-this-c-sharp
– barlop – 2015-06-18T02:15:55.770I find that for redireciton . utf8 works in c sharp though unicode doesn't – barlop – 2015-06-20T18:01:45.160
Many thanks for your answers, finally got it: whatever the session settings are, you must redefine stdout and stderr. For Java, do something like: myStdOut = new PrintWriter( new OutputStreamWriter( System.out, "UTF8" )); see this post:https://poeticcode.wordpress.com/2009/01/19/systemout-and-utf8/ . Many thanks to this contributor. Not sure at this time what to do to deal with System.in.
– Grubert – 2015-06-22T08:57:52.063@Grubert paste better you mean
PrintWriter out = new PrintWriter(new OutputStreamWriter(System.out)); out.println(“some-utf8-string”);i'm not in front of java right now but you could experiment with InputStreamReader(System.in) and a readLine() You should ask on stackoverflow, it's a coding issue as you know – barlop – 2015-06-25T11:58:49.190
