    "T": {
        "field": "title",
        "operations": [
            {
                "function": "replace",
                "regex": "\\s*[.:;?!|].*",
                "replacement": ""
            },
            {
                "function": "replace",
                "regex": " \\- ",
                "replacement": " ",
                "flags": "g"
            },
            {
                "function": "replace",
                "regex": "<i>|<\/i>|<b>|<\/b>|<sup>|<\/sup>|<sub>|<\/sub>|<span[^>]+>|<\/span>",
                "replacement": "",
                "flags": "g"
            },
            {
                "function": "replace",
                "regex": "[\\\/()~!@#$%^&*{«»„““”‘’|….,;`^<>'}+:?!®©]*",
                "replacement": "",
                "flags": "g"
            },
            {
                "function": "trim"
            }
        ]
    },
    "O": {
        "field": "extra",
        "operations": [
            {
                "function": "replace",
                "regex": "[\\s\\S]*original-date: (\\d{4})[\\s\\S]*|[\\s\\S].*[\\s\\S]",
                "replacement": "$1"
            }
        ]
    }
}

The %T wildcard does the following:

1. Truncate the title after any of ., :, ;, ?, !, |.
2. Remove - (hyphen surrounded by spaces).
3. Remove formatting tags.
4. Remove punctuation (keeps hyphens in compound words).
5. Trim whitespace at the beginning and end.

The %O wildcard does the following:

1. Extract the year of the original-date entry in the extra field if present. Otherwise return the empty string.

The %O wildcard can be used with a fallback like {%O|%y} which expands to the original date if it is present and the regular date otherwise.

To use the wildcards, remove all newlines, go to the config editor in Zotero (Preferences -> Advanced -> Config Editor). and paste it as the value for the extensions.zotfile.wildcards.user property.

Where the | fallback is documented? In my tests, it seems like if both %O and %y give results both will appear in the result.

You have a fine collection of operations here. I also needed to replace various dashes and used the following successfully

{
  "function": "replace",
  "regex": "[\\u2010-\\u2015\\u002D\\u2212\\uFE58\\uFE63\\uFF0D]",
  "replacement": "-"
}
