问下大家,我在 flink 1.11 sql client 中执行 ```sql CREATE TABLE `test16` ( `c_first` varchar(16) CHARACTER SET `UTF-16LE` )WITH ('connector' = 'blackhole'); ```
是可以成功创建一张表的。 而执行 ```sql CREATE TABLE `test8` ( `c_first` varchar(16) CHARACTER SET `utf8mb4` )WITH ('connector' = 'blackhole'); ``` 则会报错: [ERROR] Could not execute SQL statement. Reason: java.lang.NullPointerException: utf8mb4 从官网文档中查到支持的字符集有 'US-ASCII', 'ISO-8859-1', 'UTF-8', 'UTF-16BE', 'UTF-16LE', 'UTF-16'. 请问出于什么样的考量不支持 utf8mb4 字符集呢,未来有支持打算吗? -- Sent from: http://apache-flink.147419.n8.nabble.com/
