[jira] [Commented] (LANG-1282) StringUtils#normalizeSpace normalizeSpace should not replace non-breaking spaces with normal whitespace

["Duncan Jones (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-1282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15719574#comment-15719574 ] 

Duncan Jones commented on LANG-1282:
------------------------------------

I agree with this. 

If {{Character.isWhitespace()}} is the test, then the Javadocs also need to be updated to make this crystal clear. The current documentation waffles on a bit about XML vs Java white-space conventions; IMO we should just concisely explain what this method does.

> As of 3.4 StringUtils#normalizeSpace does not normalize non-breaking whitespace anymore. Therefore it shouldn't replace a non-breaking whitespace white breaking whitespace, but both assertions succeed:
> {code}
> assertEquals("a b", StringUtils.normalizeSpace("a\u00A0b"));
> assertEquals("a  b", StringUtils.normalizeSpace("a\u00A0 b"));
> {code}
