Currently, if you have a fully-functioning data-driven UI, and copy-paste text from Photoshop that includes a manual line break (creating by hitting Shift+Enter), into a Data Value in Studio, it will result in a breakage of the UI.

Repro Steps:

1) Open any Studio Project that is Data-Driven (The 'Squad' Sample is a great choice)
Observe how the screen is all rendering as expected.

2) Navigate to the Data Panel, enter the currently-active DataSet, and select it to open it in the Properties Panel.
3) Identify any String-type Data Property (I selected the name of the first Soldier Katherine Towle).
4) Replace the Data's Value with the text included in the attached ForbiddenCharacter.xml document.

Observe how the Page continues to render as expected.

5) Restart Studio, and re-open the Project.

Observe how the entire UI ceases to render.

Expected Results: Either unsupported characters are forbidden and give a warning to the user, OR characters are at least supported enough to not break the UI (even though the character may not render or be interpreted correctly)
