- When a surrogate pair is about to be split down the middle we reduce the size of our split by 1 character. This way we split right before a surrogate pair. In the case of zero width joiners, if we split on a zero width joiner we still render valid bytes because the zero width joiner by itself can stand alone.
- Added tests for the various split cases.
#2470
We don't really want to ship what we have as a contract. As an emergency
measure we are making it into internal extension methods so we can have
a do-over in 2.1.
- Rename `CSharpRenderingContext` => `CodeRenderingContext`.
- Rename `CSharpCodeWriter` => `CodeWriter`
- Rename `BasicWriter` => `IntermediateNodeWriter`
- Rename `...BasicWriter` => `...NodeWriter`
- Made `CodeRenderingContext` a public abstract API. Left temporary TagHelper pieces in the class since these will be removed soon.
- Moved several `CodeRenderingContext` methods into extension methods. These make use of the Items collection.
- Moved the reporting of missing code target extensions into the `ExtensionIntermediateNode`. This is the integration point of `CodeTarget`s and `CodeRenderingContext`s; therefore, it made more sense existing there.
- Left SetRenderChildren/SetRenderNode as extension methods due to how they're wired up. Aka, to create a `CodeTarget` you need a `CodeRenderingContext`... To Create a `DocumentWriter` you need a `CodeTarget`... To set the render methods on the context you need a `DocumentWriter`.
- Updated tests to utilize the new code renering constructs.
- Moved code generation testability features from `CSharpLoweringPhase` to the `CodeRenderingContext.Items`.
