Magento 2 Migration Tool Config Error

[dhammerindy]

I am attempting to test data migration from a testing/development server (1.9.2.2) to a test version of Magento 2.0.2.  I am having a problem with line 131 in the configuration tool config.xml file.  The problem relates to the crypt_key.  On 1.9.2.2 a strong key was used that included characters other than a-z and 0-9.  These characters are causing an issue with migration.  I get the following error...

[ErrorException]
DOMDocument::loadXML(): error parsing attribute name in Entity, line: 131

How can I include a key that contains special characters that will not result in the migration tool failing?

This is a sample of the current key.  Some values have been changed for this post.

"%T3!G<ZI|A6G*tLt37i96:BT_I2Y~

How can I make that work in the config?

I am attempting to use the migration tool.   The problem is with the configuration file for the tool.  It is unfortunate that Magento cannot be bothered to reply to problems like this in their forums.  Makes it very difficult for me to ever recommend their product.  It us slow, buggy and apparently poorly supported.
