Problems with special characters in project name

[b2m]

This issue describes problems with special characters in the project name and other fields from metadata.json.

To Reproduce

Steps to reproduce the behavior:

1. Create a project with special characters in the project name ("Testing äüöß").
2. Close OpenRefine and check metadata.json (everything ok!)
3. Reopen OpenRefine and check special characters in the project name ("Testing äüöß").
4. Close OpenRefine and check metadata.json (not ok!)
5. Reopen OpenRefine and check special characters in the project name ("Testing äüöß")

Current Results

The special characters are somehow completely wrong and their number doubles with each restart of OpenRefine.

Expected Behavior

Reading and writing metadata to metadata.json preserves special characters.

Screenshots

Versions

• Operating System: Windows 10
• Browser Version: Firefox 95
• JRE: 11.0.13 (using the bundled version "openrefine-win-with-java-3.5.1.zip")
• OpenRefine: observed in 3.5.0, 3.5.1 and 3.5.2

Additional context

1. The list of garbled up characters grows exponentially which results in realy large metadata.json files and OutOfMemory errors.
2. This might be related or even be the same problem as described in Out of memory errors from large metadata.json files being parsed during OpenRefine Project Open #3431.
3. I also observed this problem in metadata.json in the fields .importOptionMetadata and .preferences.entries."exporters.templating.template".

i want work on it

Thanks for volunteering! This might be easier to reproduce on Windows (but it is potentially also doable on Linux).
We have a guide for first contributions here: https://docs.openrefine.org/technical-reference/contributing#your-first-code-pull-request
Let me know how it goes!

Sir I'm new to open source
After setting it on local environment
What is the next step

[wetneb]

The steps are outlined in the link I gave you above. If you point me to a more concrete problem with any of these steps I will do my best to help you.
