--------------------------------------
Great!
> Strip UTF-8 non-character codepoints
> ------------------------------------
>
> Key: NUTCH-1026
> URL: https://issues.apache.org/jira/browse/NUTCH-1026
> Project: Nutch
> Issue Type: Bug
> Components: indexer
> Affects Versions: nutchgora
> Reporter: Markus Jelsma
> Fix For: nutchgora
>
>
> During a very large crawl i found a few documents producing non-character
> codepoints. When indexing to Solr this will yield the following exception:
> {code}
> SEVERE: java.lang.RuntimeException: [was class
> java.io.CharConversionException] Invalid UTF-8 character 0xffff at char
> #1142033, byte #1155068)
> at
> com.ctc.wstx.util.ExceptionUtil.throwRuntimeException(ExceptionUtil.java:18)
> at
> com.ctc.wstx.sr.StreamScanner.throwLazyError(StreamScanner.java:731)
> {code}
> Quite annoying! Here's quick fix for SolrWriter that'll pass the value of the
> content field to a method to strip away non-characters. I'm not too sure
> about this implementation but the tests i've done locally with a huge dataset
> now passes correctly. Here's a list of codepoints to strip away:
