Mike Beckerle commented on DAFFODIL-894:
----------------------------------------
Confirming: utf16Width 'variable' is optional in DFDL v1.0 now. We simply won't
implement this optional feature of DFDL.
> utf16Width property - unpaired surrogate behavior
> -------------------------------------------------
>
> Key: DAFFODIL-894
> URL: https://issues.apache.org/jira/browse/DAFFODIL-894
> Project: Daffodil
> Issue Type: Wish
> Components: Back End
> Affects Versions: s11
> Reporter: Mike Beckerle
> Priority: Major
>
> Part of DFDL-893 but worth carving off as a lower-priority aspect.
> This was a comment on the original January 2011 version 1.0.3 spec of DFDL.
> The Sept 2013 1.0.4 spec says:
> When utf16Width is 'variable', then on parsing an un-paired surrogate
> codepoint causes a decode error, which can be controlled via
> dfdl:encodingErrorPolicy.
> Is this the actual behavior, i.e., does ICU let us even do this? (If not then
> this will be an issue with the DFDL spec.)
