The RTF producer and parser lacked support for text lists, failed to encode
non-ASCII characters properly (\uN), and treated first-line indents (\fi) as
absolute values rather than offsets relative to left indents (\li).
Additionally, paste operations ingested application-generated RTF rather than
the native internal archive, causing image attachments and tables to be stripped
during copy-paste workflows within the application.
* AppKit/CPTextView/_CPRTFProducer.j:
- Implement RTF serialization for text lists using list tables, override tables,
\levelmarker, \levelprepend, \lsN\ilvlK tags, and \listtext marker blocks.
- Encode non-ASCII characters via \uc0\uN syntax and compute \fi indents
relative to \li.
- Omit image attachment characters from text runs and adjust run starting indices
to accommodate list markers.
* AppKit/CPTextView/_CPRTFParser.j:
- Implement pre-pass parsing for list and override tables.
- Assign shared text lists to items using \ls and \ilvl, extracting marker formats
from \levelmarker or standard number/level definitions.
- Parse \uN sequences (skipping fallback characters) and evaluate relative \fi offsets.
* AppKit/CPTextView/CPTextView.j:
- Configure paste handling to prioritize internal archives when clipboard RTF
originates from the application, ensuring image attachments and tables survive internal copy-paste.
* AppKit/CPTextView/_CPTableTextAttachment.j:
- Implement keyed archiving and decoding for table headers, rows, widths,
and configuration settings, reconstructing cell instances upon unarchiving.
* Tests/AppKit/CPRTFTest.j:
- Add comprehensive unit tests covering Unicode encoding, relative first-line indents,
TextEdit and Word list interoperability, and nested list round-trip fidelity.
* Tests/AppKit/CPTextAttachmentTest.j:
- Add test coverage for table attachment archiving.
* Tests/Manual/TextEditor/WORKLIST.md:
- Mark intra-application copy and paste testing as completed.
- Log external rich text exchange limitations as open items.
Intra-application copy and paste now fully preserves images, tables, and lists,
while RTF serialization supports Unicode and structured hierarchical lists.
