When parsing documents, we receive the document as UTF-8 encoded data which we then parse and convert the fields to java-native UTF-16 encoded Strings. We then convert these strings back to UTF-8 for storage in lucene. This patch skips the redundant conversion, instead passing lucene a direct reference to the received UTF-8 bytes when possible.
