flink sql写mysql中文乱码问题怎么办？

我看flink官网介绍Table API & SQL的时候有打印sql执行计划中使用的是UTF-16LE字符集，为什么不用UTF-8呢？乱码会不会跟这个有关？ https://ci.apache.org/projects/flink/flink-docs-release-1.13/zh/docs/dev/table/common/#%e8%a7%a3%e9%87%8a%e8%a1%a8

上述例子的结果是：

== Optimized Logical Plan == DataStreamUnion(all=[true], union all=[count, word]) DataStreamCalc(select=[count, word], where=[LIKE(word, _UTF-16LE’F%')]) DataStreamScan(id=[1], fields=[count, word]) DataStreamScan(id=[2], fields=[count, word])

== Physical Execution Plan == Stage 1 : Data Source content : collect elements with CollectionInputFormat*来自志愿者整理的flink邮件归档
