Github user PascalSchumacher commented on the issue: https://github.com/apache/commons-lang/pull/184 Thanks for the information. I did not know that `normalizeSpace` replaces non-breaking spaces with normal whitespace. Both these test succeed: ```java assertEquals("a b", StringUtils.normalizeSpace("a\u00A0b")); assertEquals("a b", StringUtils.normalizeSpace("a\u00A0 b")); ``` The argument brought forward as to why `normalizeSpace` does not normalize non-breaking space anymore was that `Character#isWhitespace` returns `false`. Like I said I do not agree with this argument.
