It was a bug, but it isn't anymore.

In earlier releases, the arguments on the escript line beginning with
%%! was passed to the virtual machine via an environment variable. As
a side effect of this the arguments was mangled a bit, causing some of
the quotation marks to disappear. This was fixed in Erts 5.7.3
(OTP-1060). The arguments are now passed to the VM as they are written
in the escript, without any mangling. Unfortunately this bug fix was
not documented. I hope that has not caused you too much trouble.
