我正在尝试制作与一个人的名字匹配的动态正则表达式。在大多数名称上都可以正常使用，直到我在名称末尾遇到带重音符号的字符为止。
示例：某些花式Namé
到目前为止，我使用的正则表达式是：
/\b(Fancy Namé|Namé)\b/i
像这样使用：
"Goal: Some Fancy Namé. Awesome.".replace(/\b(Fancy Namé|Namé)\b/i, '<a href="#">$1</a>');
这根本不匹配。如果将é替换为e，则匹配得很好。如果我尝试匹配“ Some FancyNaméa”之类的名称，则效果很好。如果我删除单词last word边界锚，它就可以正常工作。
为什么单词边界标记在这里不起作用？关于如何解决此问题的任何建议？
我已经考虑使用类似的方法，但是我不确定性能会受到什么样的影响：
"Some fancy namé. Allow me to ellaborate.".replace(/([\s.,!?])(fancy namé|namé)([\s.,!?]|$)/g, '$1<a href="#">$2</a>$3')
建议？想法？
JavaScript的regex实现不支持Unicode。它仅知道标准低字节ASCII中的“单词字符”，其中不包含é或任何其他带重音或非英语的字母。
因为é不是JS的文字字符，所以é后面加空格不能被视为文字边界。 （如果用在单词中间，例如\b，它将与Namés相匹配。）
/([\s.,!?])(fancy namé|namé)([\s.,!?]|$)/
是的，这将是JS通常的解决方法（尽管可能会有更多的标点符号）。对于其他语言，通常应使用超前/后退以避免与前后边界字符匹配，但是在JS中这些字符受支持不佳/错误，因此最好避免。
Rob是正确的。引自ECMAScript第三版：
15.10.2.6断言：
生产断言
\b的评估依据...2。调用IsWordChar（e-1）并让a为布尔结果3。调用IsWordChar（e）并让b为布尔结果
和
内部帮助函数IsWordChar ...执行以下操作：
3。如果c是下表中的六十三个字符之一，则返回true。
a b c d e f g h i j k l m n o p q r s t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 0 1 2 3 4 5 6 7 8 9 _
由于é不是这63个字符之一，因此é和a之间的位置将被视为单词边界。
如果您知道字符的类别，则可以使用否定的前瞻性断言，例如
/(^|[^\wÀ-ÖØ-öø-ſ])(Fancy Namé|Namé)(?![\wÀ-ÖØ-öø-ſ])/
[不幸的是，即使有一天Javascript应该完全和适当地支持Unicode，您也将[[still在单词边界方面要格外小心。容易误解\b的实际作用。
\b实际功能的Perl代码，无论您的模式引擎是否已由BNM升级，这都是事实： # if next is word char:
# then last isn't word
# else last isn't nonword
$word_boundary_before = qr{ (?(?= \w ) (?<! \w ) | (?<! \W ) ) }x;
# if last is word:
# then next isn't word
# else next isn't nonword
$word_boundary_after = qr{ (?(?<= \w ) (?! \w ) | (?! \W ) ) }x;
第一个就像在某个东西之前的的ASCII世界。我承认，这只是一个悲惨的情况。甚至Python都非常保守（例如，它甚至不支持递归正则表达式），does允许\b，第二个就像在它之后的\b。所使用的构造为条件表达式正则表达式“ IF-THEN = ELSE”，其一般形式为(?(COND)THEN|ELSE)。在这里，我使用的是COND测试，第一种情况是先行，第二种情况是先行。在两种情况下，THEN和ELSE子句都是否定的环顾四周，因此它们将字符串的边缘考虑在内。
我将解释有关在正则表达式here中处理边界和Unicode的更多信息。Unicode属性支持

您仅必须在Java和Javascript中使用短名称，但是Perl也允许您使用长名称，这有助于提高可读性，Perl 5.12版本支持大约3,000个Unicode属性。 Python没有值得一提的Unicode属性支持，而Ruby刚开始在1.9版本中得到它。 PCRE的支持有限，主要是Java 1.7。[Java6支持Unicode块属性，例如still
\p{InGeneralPunctuation}或\p{Block=GeneralPunctuation}，而Java7支持Unicode脚本属性，例如\p{IsHiragana}或\p{Script=Hiragana}。 [但是，它仍然不支持甚至接近full set of Unicode properties的任何东西，包括\p{WhiteSpace}，\p{Dash}和\p{Quotation_Mark}等近临界的东西，更不用说像\p{Line_Break=Alphabetic}这样的其他两部分了， \p{East_Asian_Width:Narrow}，\p{Numeric_Value=1000}或\p{Age:5.2}。
