Translation of the author's name

Hmm. We upgraded recently from 2.4.8. to 3.1.2 - for our multilingual journals, the user family and given names are only in the en_US locale part of the corresponding fields.
Is there a script or SQL command that copies them over to the other locales. The 3.1.2_preupdate_user_author_names.xml did not seem to have helped translation

Essentially I understand that for multilingual journals with very different character sets (western european, arabic, kyrillic) that multi-language fields must be offered. However, if you have, say 4 western european languages only, no user and author will understand why he has to fill out his name 4 times. From a GUI and usability perspective, this is absolute nonsense. At least there should be a process that copies over the field information.
