How to get the decimal value of Unicode characters in Java?

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

UTF-8：

著者名

decimal system:

著者名

Solution

I suspect that you are only interested in the conversion from char to int, which is implied:

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

Edit: if you want to handle proxy pairs, you can use something similar:

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);
}
