--- Comment #7 from Gijs Vermeulen gijsvrm@gmail.com --- (In reply to Gijs Vermeulen from comment #6)
I can not reproduce this with wine-2.18 following the exact instructions from comment #1. My guess is that this was fixed by: https://source.winehq.org/git/wine.git/commitdiff/ f091d9edf652eb2b45d8042c598addd7d0ef4d2c
It seems I misread the bug when I posted this. The crash is indeed gone, but Sys.setlocale("LC_CTYPE", "Chinese_China.950") still gives the aforementioned warning and prevents the attached 1.R file from opening. Wine 2.22.
