Steve Rowe commented on LUCENE-6874:
------------------------------------
bq. Thank for the fruitful discussions! I hope Steve Rowe is not unhappy
because we did not use jflex for this simple case and instead use Unicode data
with the already existing CharTokenizer.
No worries, +1 to your work Uwe. You've also laid the groundwork for future
simple Unicode property-based char tokenizers, which is nice. Thanks!

> WhitespaceTokenizer uses [Character.isWhitespace
> |http://docs.oracle.com/javase/8/docs/api/java/lang/Character.html#isWhitespace-int-]
> to decide what is whitespace. Here's a pertinent excerpt:
> bq. It is a Unicode space character (SPACE_SEPARATOR, LINE_SEPARATOR, or
> PARAGRAPH_SEPARATOR) but is not also a non-breaking space ('\u00A0',
> '\u2007', '\u202F')
> Perhaps Character.isWhitespace should have been called
> isLineBreakableWhitespace?
> I think WhitespaceTokenizer should tokenize on this. I am aware it's easy to
> work around but why leave this trap in by default?
