Nextcloud version 13:
Operating system and version Ubuntu 16.04:
Apache or nginx version Apache 2.4.18:
PHP version 7.0.25:
The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): y

Steps to replicate it:

  1. Set full user’s name with language other than English.

I’m running nexcloud on Russian language. So when i’m trying to set or change full user’s name from English language to Russian - I got annoying problem with avatar generation. I mean that instead 1st name letter as avatar symbol I always got only this:

изображение

What is it? Problem with font? I have already tried even “Times New Roman” from MS.
Problem with codepage? So where I can fix that?
