[jira] [Created] (SPARK-17299) TRIM/LTRIM/RTRIM strips characters other than spaces

Jeremy Beard created SPARK-17299:
------------------------------------

             Summary: TRIM/LTRIM/RTRIM strips characters other than spaces
                 Key: SPARK-17299
                 URL: https://issues.apache.org/jira/browse/SPARK-17299
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Jeremy Beard


TRIM/LTRIM/RTRIM docs state that they only strip spaces:

http://spark.apache.org/docs/2.0.0/api/java/org/apache/spark/sql/functions.html#trim(org.apache.spark.sql.Column)

But the implementation strips all characters of ASCII value 20 or less:
