@MBaesken I added an informative text about supported locales. I also lowered the fatal error of missing an UTF-8 locale into just a warning (for all platforms, not just AIX). Apparently it works with building on AIX for now, even with a undefined character encoding, but I will not guarantee that it will continue to work for all eternity. But a warning is probably be enough, and if it does work the user is free to try. :)
