在Java中将希腊语转换为大写 [英] Converting Greek to Uppercase in Java

问题描述

我想做的事情很简单：

String example = "Τάχιστη αλώπηξ βαφής ψημένη γη - Mary Had A Little Lamb";
String upper = example.toUpperCase();

在希腊语中，只有大写单词的第一个字母应包含重音字符。

In Greek, only the first letter of an uppercase word should contain accented characters.

// upper contains the following (incorrect) string:
// ΤΆΧΙΣΤΗ ΑΛΏΠΗΞ ΒΑΦΉΣ ΨΗΜΈΝΗ ΓΗ - MARY HAD A LITTLE LAMB

// correct string:
// ΤΑΧΙΣΤΗ ΑΛΩΠΗΞ ΒΑΦΗΣ ΨΗΜΕΝΗ ΓΗ - MARY HAD A LITTLE LAMB 

（重音很难看，但它们就在那里。）

(The accents are hard to see, but they're there.)

根据 Java 1.7文档，我应该可以通过区域设置为 toUpperCase ，如下所示：

According to the Java 1.7 documentation, I should be able to pass a locale to toUpperCase, like so:

String upper = example.toUpperCase(new java.util.Locale("el"));

但是，看起来没有 toUpperCase的具体规则正确处理希腊语。

However, it looks like there are no specific rules for toUpperCase which handle Greek correctly.

是否可以为特定区域设置定义 toUpperCase 的行为，以便我可以确保获得正确的结果？

Is it possible to define the behavior of toUpperCase for a particular locale, so that I can ensure I get the correct result?

或者，我可以编写一个实用程序类来处理这种特殊情况。但是如果可能的话，我宁愿在每个语言环境中覆盖此函数，以防其他语言出现。

Alternatively, I can just write a utility class to handle this particular case. But if it's possible, I'd prefer to override this function per locale, in case this comes up for other languages.

推荐答案

Per @ajb默认情况下不支持Java。我必须创建自己的解决方案。

Per @ajb, this is not supported in Java by default. I had to create my own solution.
