使用Java的org.apache.commons.net.telnet.TelnetInputStream类对Apache Telnet客户端进行包装，读取和处理非ASCII字符。示例代码如下：

import org.apache.commons.net.telnet.TelnetClient; import org.apache.commons.net.telnet.TelnetInputStream;

public class Example { public static void main(String[] args) { try { TelnetClient client = new TelnetClient(); client.connect("localhost", 23); TelnetInputStream in = client.getInputStream(); byte[] buffer = new byte[1024]; int read; while ((read = in.read(buffer)) != -1) { String output = new String(buffer, 0, read, "UTF-8"); System.out.println(output); } client.disconnect(); } catch (Exception e) { e.printStackTrace(); } } }

在上述示例代码中，我们使用TelnetInputStream类来读取Apache Telnet客户端的输入流，并使用UTF-8编码将字节转换为字符串。这将允许我们正确处理和显示非ASCII字符。
