I have created two pull requests to enable wiktextract to parse non-English Wiktionary dump files:
The maintainers haven't give any response yet... With these changes, the Chinese Wiktionary dump file can be parsed. For other languages, some data files need to be created first(those JSON files in the "data" folder in each projects).
All tests passed for both projects, but a lot of work is needed to fully support each new language.
