project.json parser can't handle unicode escape sequences

[Flavien]

I'm trying to have the Copyright character in my project.json file:

  "copyright": "Copyright \u00A9 2015",

however, this results in a build failure:

Oh, Dam it. Assign to my self. Please help me to place it in the right milestone @muratg

[troydai]

Fixed in e874201

[Flavien]

Thanks! So that will be shipped as part of beta8?

[troydai]

No, sorry. Unfortunately it doesn't make into beta8. I hope it doesn't significantly impact your project. Thanks for the patience.
