String fromEncodeValue =
org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.getStringFromVarCharHolder(fromEncode);
String toEncodeValue =
org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.getStringFromVarCharHolder(toEncode);
try {
String toEncodeStringValue = new
String(stringValue.getBytes(fromEncodeValue),toEncodeValue);
out.buffer = buffer;
