Arches-0.5-linux.tar.bz2 crashes on launch on Steam Deck with
I'm sorry, but an uncaught exception occurred. Before loading the script. UnicodeEncodeError: 'ascii' codec can't encode character u'\udcf6' in position 65: ordinal not in range(128)
when started through Steam (via Arches.sh) because Steam sets LC_ALL=C.
If you modify Arches.sh to say
#!/bin/sh LC_ALL=en_US.UTF-8
at the start, then the game will launch correctly in Gaming Mode.
