Hi,

currently Flink does not support this charset in a LIKE expression. This is due to a limitation in the Apache Calcite library. Maybe you can open an issue there.

The easiest solution for this is to implement your own scalar function, that does a `string.contains("XXXX")`.

Here you can find some explanation how to implement a scalar function: https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/table/udfs.html#scalar-functions

I hope that helps.

Regards,
Timo
