files terminated with null characters

As this is not valid input to solc, I suspect this has something to do with how files are stored in sanctuary. Example:

• https://github.com/tintinweb/smart-contract-sanctuary-ethereum/blob/1e69d37c1aa7b2c6dd7285f756bddaf6c129040d/contracts/mainnet/04/04e0e2dd8fdbca1d584927cdbdeb7a1314dff1f4_Bloktrade.sol

Thanks for this incredibly helpful project!
