2. They are badly displayed when exported to .pdf

3. They are badly displayed when exported to .html

4. They are badly displayed when saved as .pptx or .ppt

The situation is even worse on Libre Office (x64). When I attempt to read the demo.odp file LO becomes non-responsive and crashes!!! Then I attempt to open a new file and paste "大黃䗪蟲丸狐𧌒䒜𧀬" in, LO also becomes non-responsive and crashes!!!

I'm closing this issue because multiple test cases have been included in this issue. Each test case has its own test file and steps to reproduce. Reporting several test cases together makes it hard to communicate the status of the issue . I'm sure some of the test cases in this issue have been fixed. Please feel free to report each test case as a separate issue.

If the issues are related to file format, then each of the file format owes its own test case.
