> Provide support for Non-spacing mark/Combining Characters in Debugger
> ---------------------------------------------------------------------

> Key: DAFFODIL-2168
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2168
> Project: Daffodil
> Issue Type: Bug
> Components: Debugger
> Affects Versions: 2.4.0
> Reporter: Olabusayo Kilo
> Priority: Major
> Attachments: nonspacingmark.png, tcp.dfdl.xsd, test.dump
>
>
> Certain unicode characters are [combining
> characters|https://en.wikipedia.org/wiki/Combining_character] and can combine
> with the characters surrounding them, modifying them. This can lead to
> misalignment in our debugger.
> A possible solution could be to detect when a character is a non-spacing
> (or other combining character) and insert the appropriate number of spaces
> around it. Java's Character.getType method will return an enum about what
> type a character is. Many of these character types might need this alignment
> assistance.
> Attached is a pictorial example of the problem and the files that can be used
> to recreate the issue.
> Command run:
> {code:java}
> daffodil --trace parse -Dtransport:Protocol=6 transport:DataLength=79 -s
> tcp.dfdl.xsd test.dump{code}
