6.5-GE-2 GloriousEggroll

Running the game with Valve's Proton versions (5.13-6, 6.3-2, and Experimental) results in black rectangles being displayed instead of the Japanese in‑game text, presumably due to a font issue. No such problem happens with Proton-6.5-GE-2.

Setting launch options to LANG=ja_JP.UTF-8 %command% with a Japanese locale installed fix the minor mojibake in the out‑of‑game settings. Note that the in‑game text displays fine, even without that.
