Inconsistent encoding usages when saving/reading hippo:text

ServicingNodeIndexer is responsible for reading hippo:text to index a document.
However, it simply uses

IOUtils.toString(hippoTextBinaryValue.internalValue.getStream());

, which doesn't care the encoding of the stored bytes. As a result it uses ISO-8859-1 encoding by default, even though UTF-8 is mostly used when saving the extracted pdf text data.

So, please use

IOUtils.toString(hippoTextBinaryValue.internalValue.getStream(), "UTF-8");

instead.
