我正在寻找一种方法来计算由多个角色组成的特殊角色,但在网上找不到解决方案!

例如,我想计算字符串"வாழைப்பழம".它实际上由6个泰米尔字符组成,但在这种情况下,当我们使用常规方法查找长度时,它的9个字符.我想知道泰米尔是唯一会导致此问题的编码,如果有解决方案的话.我目前正在尝试在C#中找到解决方案.

提前谢谢=)

目前我们正在使用 Ignite 2.1 和 Spring Data Ignite Repository。我有一个服务器节点和一个带有一个缓存“TestCache”的客户端节点。当客户端连接到服务器，并且服务器节点关闭时，它将断开连接。当服务器节点重新启动时，客户端节点将重新连接。

但是，当它重新连接时，缓存“TestCache”不再可访问，但有以下例外：
