使用带有以下命令的ksql-server.properties文件启动KSQL时：
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required \
username="<username>" \
password="<password with @ and special chars>";
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
我得到一个错误：

具体来说，错误：
Value not specified for key 'â' in JAAS config
让我失望-JAAS配置中的键应该仅是用户名和密码-对吗？
在我的融合服务器中使用完全相同的用户名密码和SASL_Plaintext创建了一个client.properties文件。
