fix build script for Non-English environment.

I want to test my modified version of playbook, but the output of the
test target seems having a broken xml format.

It turns out that I use the Chinese environment and powershell use the
Chinese encoding to read and write `playbook.conf` file, that would
break the `Description` content which contains special characters.

So here is the fix, simply add `-Encoding` to the read and write
commands.
