Description

Currently the list of supported charsets in decode() is not stable and fully depends on the used JDK version. So, sometimes user code might not work because a devop changed Java version in Spark cluster. The ticket aims to restrict the list of supported charsets by:

'US-ASCII', 'ISO-8859-1', 'UTF-8', 'UTF-16BE', 'UTF-16LE', 'UTF-16'
