    Another test case for Unicode column names in ANALYZE COLUMN:
    
    ```Scala
        // scalastyle:off
        // non ascii characters are not allowed in the source code, so we 
disable the scalastyle.
        val colName1 = "`列1`"
        val colName2 = "`列2`"
        // scalastyle:on
        withTable(table) {
          sql(s"CREATE TABLE $table ($colName1 int, $colName2 double) USING 
PARQUET")
          sql(s"INSERT INTO $table SELECT 1, 3.0")
          sql(s"ANALYZE TABLE $table COMPUTE STATISTICS FOR COLUMNS $colName2, 
$colName1")
          ...
        }```
