In a support discussion titled ‘The 'admins' and 'moderators' groups name are hardcoded?’, Don reports that the group names admins and moderators are not translating despite updating the relevant locale strings (groups.default_names.moderators, groups.default_names.admins). He includes screenshots showing the untranslated names in group messages, category security settings, and dropdowns. gerhard explains that group names are validated like usernames and may require enabling the unicode_usernames site setting if non-ASCII characters are used. Don confirms this was his issue — he had forgotten to enable unicode_usernames on his current site (though it worked on a test site where it was enabled). He opts to use non-accented names for now and later reports that after updating, the translations work as expected. The issue stems from group name validation rules, not hardcoding, and can be resolved by adjusting site settings or using ASCII-compliant names. Don thanks gerhard for the help.
Hello,
I’ve noticed the admins and moderators group name are not translatable. Is there something I missed? I remember as if these could have been translated in the past. But I’m not sure about that.
I changed these strings:
groups.default_names.moderators
groups.default_names.admins
But it didn’t change on these places I noticed.
Group messages
Category Security settings
Group page dropdown select
Thank you 
The group names should be updated every 12 hours by a background job as long as your new group names are valid usernames, because group names are validated against the same rules as usernames.
You might need to update the unicode_usernames site setting if your translations contain non-ASCII characters.
Hello Gerhard,
Oh yeah I think this is the problem for me. 
I always forget this. 
I remembered for this correctly because one of my test site the group names changed right, but the unicode_usernames setting was enabled for testing purpose. I forgot this step here.
But I didn’t enable this setting for now because I don’t want to enable it for usernames. So now I use names without accents in group names. We’ll see how it goes.
Thank you so much for your help!
Edit: Just updated now and everything works as expected! Thanks again!
