File builder freezes upon encountering a module with a special character

[antlersss]

What I expected to happen
I expected the builder to either throw an exception stating that my module name was invalid, or that it would accept the module outright.

What happened instead
The builder gets stuck, saying it's still building. The only way to stop it is to exit the program.

How do I reproduce this?
Reliable steps that should produce this issue:

1. Create a package with a special character (in my case, it was -)
2. Add requires([package name]) somewhere in your script.
3. Attempt to build.

Screenshots and Project zip file
N/A

Additional info
It's alright if the program can't accept special characters, just a simple check that any provided modules contained them and alerting the user about it would be helpful.
