Errors with String Type Constants

[Carter12s]

@adrienbarral and @philbest seem to be having some problems with constants with string types, and have been cooking on some PRs to improve the situation.

See: #232, #233, #234

This is a tracking issue for the underlying problem.

I don't have full knowledge of what the underlying issue is, but it appears that our message generation code doesn't handle string constant's values correctly when there are # signs in the constant.

@adrienbarral / @philbest, let me know if there is anything I can do to help you with your solutions. This is fully a bug and would love to get it fixed!
