Summary: DSL expressions fail on attribute with special characters
Key: SPARK-43142
URL: https://issues.apache.org/jira/browse/SPARK-43142
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.4.0

Expressions on implicitly converted attributes fail if the attributes have
names containing special characters. They fail even if the attributes are
backtick-quoted:
{code:java}
scala> import org.apache.spark.sql.catalyst.dsl.expressions._
import org.apache.spark.sql.catalyst.dsl.expressions._
scala> "`slashed/col`".attr
res0: org.apache.spark.sql.catalyst.analysis.UnresolvedAttribute = 'slashed/col
scala> "`slashed/col`".attr.asc
org.apache.spark.sql.catalyst.parser.ParseException:
mismatched input '/' expecting {<EOF>, '.', '-'}(line 1, pos 7)
== SQL ==
slashed/col
