Repro steps.

1. Create folder with a '#' in the name. (eg. '#project' or 'te#st')
2. ng new project
3. cd project
4. npm install
5. ng build (or ng serve)

The log given by the failure.

You an error similar to the following:
ERROR in Could not resolve "C:/JesseDev/Te" from "C:/JesseDev/Te".

Desired functionality.

Accept the use of '#' in folder names leading to the project.

Mention any other details that might be useful.

I spent a good half day trying to figure this out. Sure, better naming conventions could have prevented this, but I would still consider it a bug. A better error message would have been appreciated (invalid folder structure maybe?)
Also, if you use the --watch flag on build or serve, then trigger a rebuild, it works fine.
