PSO2 on Linux casefolding guide

Note
This guide is primarily written for the Global Steam version of the game, however it should also apply more or less the same with other versions like Global EGS version, and also Japanese version as well.

Proton-GE includes a patch which allows you to not do any of this, however, I'd still recommend following this guide over using Proton-GE as it's proven to be more reliable so far, and also applicable to any other games.

I do not hold any liability for what happens if you mess up, be warned.
I would recommend reading through the entire guide first even if certain parts may not apply to you.
