error when running vagrant-build

I had an error when running vagrant as documented on the frontpage. I think it's related to my account name that has unicode:

/home/anarcat/vagrant/projects/1.x-test/.config/config.rb:10: invalid multibyte char (US-ASCII)
/home/anarcat/vagrant/projects/1.x-test/.config/config.rb:10: syntax error, unexpected $end, expecting '}'
                "git_name" => "Antoine Beaupré",

I am not sure how to fix this. Here is the full log.

anarcat@marcos:~$ drush vagrant-build --blueprint=aegir
This appears to be your first time running Drush Vagrant or your user settings (~/.drushrc.php) have been deleted.
Drush Vagrant Integration requires those settings in order to function properly.
Proceed? (y/n): y

The directory you specified for your projects (/home/anarcat/vagrant/projects) does not appear to exist. Create it now?: y
The name of your project may be used in URLs, and so should only contain lower-case letters and numbers.
It may also contain hyphens (-) and dots (.), so long as they do not come at the beginning or end of the name.
What would you like to call your project?: 1.x-test
Would you like to generate entries in /etc/hosts for the VMs in your project? (y/n): n
Would you like to generate Drush aliases for your project? (y/n): y
You are about to:
  * Create a new project called "1.x-test" at "/home/anarcat/vagrant/projects/1.x-test".
  * Generate Drush aliases for the project and VMs.
  * Launch the project VMs immediately.
  * Build the project using the "aegir" blueprint from the "aegirup" extension.
Do you want to proceed with initializing the project? (y/n): y
