Y'all,
  I'm glad to share the code I developed to help managing gigantic MARC files, many of which contain non-English records. I believe this tool could be beneficial to others facing similar challenges. Your feedback is highly appreciated.
Here is the link of the repository: GitHub - hmakki72/pymarc_utilities: Pymarc Utilities is a set of functions aimed to help manuplating large size MARC files. Pymarc Utilities works with Pymarc library for working with bibliographic data encoded in MARC21.<https://github.com/hmakki72/pymarc_utilities>

Cheers,
