A warning is now displayed when a file's contents include bidirectional Unicode text. Such text can be interpreted or compiled differently than it appears in a user interface. For example, hidden, bidirectional Unicode characters can be used to swap segments of text in a file. This can cause code to appear one way and be interpreted or compiled another way.

Seems overrated to me. We have known about RTL exploits since 2000, why now in news?
I think the reason is obvious. To make people more aware of the situation.
