大写与标题之间的区别 [英] Difference between uppercase and titlecase

问题描述

大写和标题之间的区别是什么。
坦率地说，我之前从未听说过 titlecase 。

What's the difference between uppercase and titlecase. Frankly, I never heard of titlecase before.

在java中，两者都有单独的方法：

In java there are seperate methods for both:

• Character.isTitleCase（char）


• Character.isUpperCase（char）

• Character.isTitleCase(char)
• Character.isUpperCase(char)

有些网站将其定义如下：

Some websites define it as follows:

TitleCase：匹配组合大写字母和小写字母的字符，例如Nj和Dz

TitleCase: Matches characters that combine an uppercase letter with a lowercase letter, such as Nj and Dz

但必须有更多： isTitleCase（char）方法只接受1个字符。所以 - 如果是这种情况 - 那么这个方法至少需要2个字符。

But there must be more to it: the isTitleCase(char) method only accepts 1 character. So - if this was the case - then this method would need at least 2 characters.

推荐答案

它只接受一个 Unicode 字符。事实证明DŽ实际是只有一个字符：看它以等宽字体显示的方式：DŽ。标题版本为Dž和小写版本dž也存在。

It accepts only one Unicode character. It turns out that DŽ actually is only one character: look how it shows in monospaced font: DŽ. The titlecase version is Dž and a lowercase version dž exists as well.
