>                 Key: DAFFODIL-894
>                 URL: https://issues.apache.org/jira/browse/DAFFODIL-894
>             Project: Daffodil
>          Issue Type: New Feature
>          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.)
