What are you doing that causes configuration values to be unescaped?
The only thing I can think of is making your config file a Lua script,
or injecting strings from it into loadstring()'d code. If you're not
careful, either of these can be major security issues, and if you are
doing this for a good reason, look at string.format('%q', foo).
