There are several issues on the pulumi GitHub about pulumi not working when windows is in another language than English because of special characters. The only workaround is changing the OS language. I don't know since when this stop working but it was working in pulumi v1. I am organizing a workshop about pulumi in my company and tell the participants to all change their OS language doesn't seem a very good option but I don't see another one. any idea when this will be corrected ?

We've prioritized this due to the increasing number of reports we've heard in the last few weeks - we're hoping to address in the next ~week (0.37 milestone on GitHub).
