> Unparser escaping doesn't escape all the delimiters
> ---------------------------------------------------
>
> Key: DAFFODIL-2089
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2089
> Project: Daffodil
> Issue Type: Bug
> Components: Unparsing
> Affects Versions: 2.3.0
> Reporter: Michael Beckerle
> Assignee: Josh Adams
> Priority: Major
> Fix For: 2.4.0
>
>
> When unparsing, suppose you have a sequence with an escape scheme defined,
> and multiple separators:
> <xs:sequence dfdl:separator="| ; ,">
> Suppose dfdl:generateEscapeBlock='whenNeeded'
> When unparsing, the sequence's children will be output using "|" separators.
> Any "|" found in the data will cause escaping (either with the escape
> character or by surrounding the element value with escape block.)
> The bug is this. If the data contains any of the OTHER separators, no
> escaping is done.
> That means the output data might contain unescaped separators.
> This will cause a subsequent re-parse of this data to interpret those
> unescaped separators as actual separators, which is broken.
> The escaping of the data on unparsing needs to escape not only the canonical
> first separator, but all separators.
