Unsuccessful filename normalization

[gy-mate]

I tried normalizing a file's name on an APFS volume:
~ % jaso "/Volumes/temp/RE_ Önkormányzati REDACTED.msg -> /Volumes/temp/RE_ Önkormányzati REDACTED.msg DONE; 1 files in 0.003973321 seconds

But jaso didn't normalize the filename as

• I still can't copy the file to an SMB server due to filename length limitation met by the filename being kept in NFD
• when I run the command again, it tries normalizing the filename again:
  ~ % jaso "/Volumes/temp/RE_ Önkormányzati REDACTED.msg -> /Volumes/temp/RE_ Önkormányzati REDACTED.msg DONE; 1 files in 0.006861128 seconds

Or does jaso do the normalization successfully anyway and the problem might be somewhere else, like

• APFS denying the change of filename from NFD to NFC or
• when copying to an SMB server, Finder.app copies the filename as NFD?

Thank you for your help in advance!
