Flink SQL csv格式分隔符设置失败怎么解决?

Flink 版本:1.11.1 我的flink sql: create table stream_tmp.t1( log string) with ( 'connector' = 'kafka', 'topic' = 't1', 'properties.bootstrap.servers' = 'xxxxx:9092', 'properties.group.id' = 'flink_test_01', 'scan.startup.mode' = 'latest-offset', 'format' = 'csv', 'csv.field-delimiter' = '\n'

); 提交到flink sql执行引擎中(获取sql,执行sql内容),报不认识'\n',内容如下: Caused by: org.apache.flink.table.api.ValidationException: Option 'csv.field-delimiter' must be a string with single character, but was: \n at org.apache.flink.formats.csv.CsvFormatFactory.validateCharacterVal(CsvFormatFactory.java:183) at org.apache.flink.formats.csv.CsvFormatFactory.validateFormatOptions(CsvFormatFactory.java:158) at org.apache.flink.formats.csv.CsvFormatFactory.createDecodingFormat(CsvFormatFactory.java:70) at org.apache.flink.table.factories.FactoryUtil$TableFactoryHelper.lambda$discoverOptionalDecodingFormat$1(FactoryUtil.java:430) ... 42 common frames omitted

不明白为什么把'\n'识别成两个字符了*来自志愿者整理的flink邮件归档
