I ran into a problem where the solution seems to be to rename the "product name" property of my project.
I have tried to find an official description of this property, but I failed. What I did find was some Apple documentation that described it as "user facing". It's hard to accept that a user facing property doesn't reliably allow for anything but ASCII, so I have to ask: what is the purpose of "product name"? (other than an intermediary to derive other properties from)
Update: Also, if possible, would be interested in some sort of documentation. I've googled site:apple.com ios PRODUCT_NAME
without much success.
