+## Use `find -print0` or `find -exec` to better handle non-alphanumeric filenames.
+
+### Problematic code:
+
+```sh
+ls | xargs wc -w
+```
+
+### Correct code:
+
+```sh
+find . -maxdepth 1 -print0 | xargs -0 wc -w
+```
+
+```sh
+find . -maxdepth 1 -print0 -exec wc -w
+```
+
+### Rationale:
+
+Using `-print0` separates each output with a NUL character, rather than a newline, which is safer to pipe into `xargs`. Alternatively using `-exec` avoids the problem of piping and parsing filenames in the first place.
+
