If you enter a string with an apostrophe ’ into the Project Name field e.g. “Wood in T’hole” then packaging for Windows will fail for a non-obvious reason. The project is a mixed code/BP one.
The string makes it into a PCH #define which won’t compile.
I’ve tested this in 4.14 and 4.15, but I’m not seeing a packaging failure. When I entered a name with an apostrophe, such as That’s Incredible, it packaged fine without an issue.
Would you mind providing the logs from your project’s Saved->Logs folder so I can take a closer look at your errors?
Could you test this again in a clean project? I’ve given it a try and it doesn’t appear to be causing a packaging failure on my end, even when I use the exact name you’ve provided.
