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"
FalseI think this bug isn't controversial like #3307 (closed) and #3309 (closed) since there is no possible information loss.
