如何在Java中获取unicode字符的十进制值？ [英] How do I get the decimal value of a unicode character in Java?

问题描述

我需要一种编程方式来获取String中每个字符的十进制值，以便我可以将它们编码为HTML实体，例如：

I need a programmatic way to get the decimal value of each character in a String, so that I can encode them as HTML entities, for example:

UTF-8：

著者名

十进制：

著者名

推荐答案

我怀疑你只是对从 char 到 int ，这是隐含的：

I suspect you're just interested in a conversion from char to int, which is implicit:

for (int i = 0; i < text.length(); i++)
{
    char c = text.charAt(i);
    int value = c;
    System.out.println(value);
}

编辑：如果你想处理代理对，你可以使用类似的东西：

If you want to handle surrogate pairs, you can use something like:

for (int i = 0; i < text.length(); i++)
{
    int codePoint = text.codePointAt(i);
    // Skip over the second char in a surrogate pair
    if (codePoint > 0xffff)
    {
        i++;
    }
    System.out.println(codePoint);
}
