[GROOVY-8982] sprintf breaks encoding on Windows

Description

 

On Windows when running groovy from command line this code does not write proper UTF-8 character into the file:

def out=new PrintStream(new File('test.txt'), 'UTF-8')
out.println sprintf('%s', '\u0439')"

while String.format() does it right:

def out=new PrintStream(new File('test.txt'), 'UTF-8')
out.println String.format('%s', '\u0439')"

Now if I add JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8 before groovy command it works properly. But the problem is that sprintf() does not write to output stream so it should keep Unicode character properly encoded without -Dfile.encoding options.
