>          Components: SQL

> Currently, Spark doesn't support literals with the Char (java.lang.Character) type. For example, the following code throws an exception:
> {code}
> val df = Seq("Amsterdam", "San Francisco", "London").toDF("city")
> df.where($"city".contains('o')).show(false)
> {code}
> It fails with the exception:
> {code:java}
> Unsupported literal type class java.lang.Character o
> java.lang.RuntimeException: Unsupported literal type class java.lang.Character o
> at org.apache.spark.sql.catalyst.expressions.Literal$.apply(literals.scala:78)
> {code}
> One of the possible solutions can be automatic conversion of Char literal to String literal of length 1.
