Looks like you left out the operators, but I'm interpreting you to want to know how various Java APIs handle those characters.
看起来您遗漏了运算符，但我将您解释为想知道各种 Java API 如何处理这些字符。
The Java handling of these characters is determined by their Unicode character properties. See the Unicode spec to see what properties they have, and thus what the different functions in Character return for them.
Java 对这些字符的处理由它们的 Unicode 字符属性决定。请参阅 Unicode 规范以了解它们具有哪些属性，以及 Character 中的不同函数为它们返回的内容。
www.unicode.org will tell you all you ever wanted to know about Unicode properties.
www.unicode.org 将告诉您所有您想知道的有关 Unicode 属性的信息。
