Kristian Waagan updated DERBY-5682:
-----------------------------------
Attachment: derby-5682-1b-use_supported_encoding.diff
Thanks for looking into the naming conventions, Knut Anders.
The relevant Derby class ([1]) uses UnicodeBigUnmarked, which was what led me
to the encoding doc. As the recommendation on this is to never remove an alias,
I think UnicodeBigUnmarked should work for all VMs that have been around for a
while - the fact that it is listed as a canonical name in the
Internationalization Guide suggests so too.
However, it appears to me that it is easier to determine that UTF-16BE is
always supported ([2]) since it is listed in the API Specification (the
Javadocs), so I'm using it instead in patch 1b (attached).
[1] CharacterEncoding in the drda package, there's one for the client side too.
[2] The encoding doc/guide introduced UTF-16BE as a canonical name for the
java.nio package in J2SE 1.4, whereas UnicodeBigUnmarked was the canonical name
originally used in the Sun JDK.
