Description

I tried to run LocalizedDisplayScriptTest on a JVM on which support for extra encodings had been removed, and then it failed like this:

1) LocalizedDisplay(org.apache.derbyTesting.functionTests.tests.i18n.LocalizedDisplayScriptTest)java.io.UnsupportedEncodingException: EUC_JP

According to the javadoc for java.nio.charset.Charset, JVM implementations are only required to support these encodings: US-ASCII, ISO-8859-1, UTF-8, UTF-16BE, UTF-16LE, UTF-16.

On platforms that don't support EUC_JP, we should skip this test. Or, alternatively, we could change the encoding used in the test to one of the encodings that are supported on all platforms.
