slor 搜索引擎不带重音

Strings can create a whole host of problems within any programming language.  Whether it's a simple string, a string containing emojis, html entities, and even accented characters, if we don't scrub data or make the right string handling choices, we can be in a world of hurt.

字符串可以在任何编程语言中产生很多问题。 无论是简单的字符串，包含表情符号，html实体甚至是带重音符号的字符串，如果我们不清理数据或做出正确的字符串处理选择，我们可能会遭受重创。

While looking through [Joel Lovera's JSTips repo][Joel Lovera_s JSTips repo], I spotted a string case that I hadn't run into yet (...I probably have but didn't notice it):  sorting accented characters to get the desired outcome.  The truth is that accented characters are handled a bit differently than you'd think during a sort:

在翻阅[Joel Lovera的JSTips回购时][Joel Lovera_s JSTips repo] ，我发现了一个尚未遇到的字符串情况(...我可能有但没有注意到)：排序带重音的字符以获得所需的结果。 事实是，重音字符的处理方式与您在排序时所想的略有不同：

// Spanish
    ['único','árbol', 'cosas', 'fútbol'].sort();
    // ["cosas", "fútbol", "árbol", "único"] // bad order
    
    // German
    ['Woche', 'wöchentlich', 'wäre', 'Wann'].sort();
    // ["Wann", "Woche", "wäre", "wöchentlich"] // bad order

Yikes -- accented characters don't simply follow their unaccented character counterparts.  By taking an extra step, i.e. `localeCompare`, we can ensure that our strings are sorted in the way we likely wanted in the first place:

Yikes-重音符号不仅仅跟随其未重音符号对应。 通过采取额外的步骤(即`localeCompare` ，我们可以确保首先以可能的方式对字符串进行排序：

['único','árbol', 'cosas', 'fútbol'].sort(function (a, b) {
      return a.localeCompare(b);
    });
    // ["árbol", "cosas", "fútbol", "único"]
    
    ['Woche', 'wöchentlich', 'wäre', 'Wann'].sort(function (a, b) {
      return a.localeCompare(b);
    });
    // ["Wann", "wäre", "Woche", "wöchentlich"]
    
    // Or even use Intl.Collator!
    ['único','árbol', 'cosas', 'fútbol'].sort(Intl.Collator().compare);
    // ["árbol", "cosas", "fútbol", "único"]
    
    ['Woche', 'wöchentlich', 'wäre', 'Wann'].sort(Intl.Collator().compare);
    // ["Wann", "wäre", "Woche", "wöchentlich"]

Localization is already a big challenge without the added confusion that comes with accented characters.  Keep `localeCompare` and `Intl.Collator` in mind every time you want to sort strings!

没有重音字符带来的额外混乱，本地化已经是一个巨大的挑战。 每当您想对字符串进行排序时，请记住`localeCompare`和`Intl.Collator` ！
