Robert Muir commented on LUCENE-6874: ------------------------------------- You can add a CharTokenizer to ICU analysis module that just looks like this: {code} protected boolean isTokenChar(int c) { return !UCharacter.isUWhiteSpace(c); } {code} If you are not happy with it needing ICU library, the definition of this property in ICU is "Space characters+TAB+CR+LF-ZWSP-ZWNBSP" (http://icu-project.org/apiref/icu4j/com/ibm/icu/lang/UProperty.html#WHITE_SPACE) so it shouldn't be hard to implement with just the jdk, but I do not know about the efficiency of that. Either way, I think it should just be a different tokenizer. > WhitespaceTokenizer should tokenize on NBSP > ------------------------------------------- > > Key: LUCENE-6874 > URL: https://issues.apache.org/jira/browse/LUCENE-6874 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/analysis > Reporter: David Smiley > Priority: Minor > > WhitespaceTokenizer uses [Character.isWhitespace > |http://docs.oracle.com/javase/8/docs/api/java/lang/Character.html#isWhitespace-int-] > to decide what is whitespace.
