Set the channel encoding to UTF-8:

You can use a preprocess script that will convert Windows-1252 to UTF-8.
if (java.util.Arrays.equals(bytesIn, new java.lang.String(bytesIn, "UTF-8").getBytes("UTF-8"))) {
// UTF-8 is probably what we have...
bytesOut = bytesIn;
} else {
// Try to convert between Windows-1252 to UTF-8.
bytesOut = new java.lang.String(bytesIn, "Windows-1252").getBytes("UTF-8");
}
