I-485/I-131: Can Applicant Sign In Native, Non-Roman Script?

[ApplicantX]

For I-485 and I-131, is it acceptable for a non-English-speaking applicant whose alphabet/script is non-Roman to sign their name in their native script (ex: Chinese hanzi)?

Thank you.

A signature can be anything; it doesn't have to be a script.
