+### What it does
+Checks for non-ASCII characters in string and char literals.
+
+### Why is this bad?
+Yeah, we know, the 90's called and wanted their charset
+back. Even so, there still are editors and other programs out there that
+don't work well with Unicode. So if the code is meant to be used
+internationally, on multiple operating systems, or has other portability
+requirements, activating this lint could be useful.
+
+### Example
+```
+let x = String::from("€");
+```
+
+Use instead:
+```
+let x = String::from("\u{20ac}");
+```
