#4006: System.Process doesn't encode its arguments.

---------------------------------+------------------------------------------
System.Process doesn't encode strings while creating new processes. It
truncate them instead. Here is simple test case. testUnicode should always
return True but does so only for ASCII string.
{{{
testUnicode :: String -> IO Bool
testUnicode str = ((== str) . init) `fmap` (readProcess "echo" [str] "")
}}}
In GHCi I get following:
{{{
*Main> testUnicode "It works here"
True
*Main> testUnicode "А здесь сломалось"
False
}}}
I think this bug isn't controversial like #3307 and #3309 since there is
no possible information loss.
