We've created an index from a number of different documents that are supplied by third parties. We want the index to only contain UTF-8 encoded characters. I have a couple questions about this:
1) Is there any way to be sure during indexing (by setting something in the solr configuration?) that the documents that we index will always be stored in utf-8? Can solr convert documents that need converting on the fly, or can solr reject documents containing illegal characters? 2) Is there a way to scan the existing index to find any string containing non-utf8 characters? Or is there another way that I can discover if any crept into my index?
