The structure of the very special hidden_unicode_codepoints.rs code has a documentation block that includes a left-to-right reversal character.

Its useful that it does this, because it demonstrates the problem that the associated lint is talking about.

However, from what I can tell, its presence in the file is causing the Firefox Inspector to present the remainder of the file in a funny way. See attached image.

This is truly a minor hiccup, since we expect to see these text flow characters to occur only in very rare circumstances in our source code. Still, it would be nice if we could figure out a way to structure that source file that did not cause the Web Browser's inspector functionality to act so oddly.
