Which characters are allowed in a VS project name?

Question

Does anyone know which characters are allowed in a VS project name? Is there a reference somewhere?

Answer 1

• Cannot contain any of the following characters: / ? : & \ * " < > | # %
• Cannot contain unicode characters
• Cannot contain surrogate characters
• Cannot be reserved names including 'CON', 'AUX', 'PRN', 'COM1' or 'LPT2'
• Cannot be '.' or '..'

I obtained this information by trying to create a project with a character I knew would not be accepted. I.e. a character that is not allowed in NTFS file paths. I.e. I used a project with the name | to get the error.
