邮件已在这里存档(花了我几秒钟),在介绍中甚至提到了空白表

static $whitespace = array(
    "SPACE" => "\x20",
    "NO-BREAK SPACE" => "\xc2\xa0",
    "OGHAM SPACE MARK" => "\xe1\x9a\x80",
    "EN QUAD" => "\xe2\x80\x80",
    "EM QUAD" => "\xe2\x80\x81",
    "EN SPACE" => "\xe2\x80\x82",
    "EM SPACE" => "\xe2\x80\x83",
    "THREE-PER-EM SPACE" => "\xe2\x80\x84",
    "FOUR-PER-EM SPACE" => "\xe2\x80\x85",
    "SIX-PER-EM SPACE" => "\xe2\x80\x86",
    "FIGURE SPACE" => "\xe2\x80\x87",
    "PUNCTUATION SPACE" => "\xe2\x80\x88",
    "THIN SPACE" => "\xe2\x80\x89",
    "HAIR SPACE" => "\xe2\x80\x8a",
    "ZERO WIDTH SPACE" => "\xe2\x80\x8b",
    "NARROW NO-BREAK SPACE" => "\xe2\x80\xaf",
    "MEDIUM MATHEMATICAL SPACE" => "\xe2\x81\x9f",
    "IDEOGRAPHIC SPACE" => "\xe3\x80\x80",
);

Answer 2

多年以后,在查找unicode空白字符时,这个问题在Google上仍有最佳结果.devio的答案很棒,但不完整.在撰写本文时(2017年10月),维基百科有一个空格字符列表:https://en.wikipedia.org/wiki/Whitespace_character

此列表指定了25个代码点,而当前接受的答案列表为18.包括其他七个代码点,列表为:

U+000A  line feed
U+000B  line tabulation
U+000C  form feed
U+000D  carriage return
