+Simplest thing to do is use built in functionality to search and remove in command.
+Here is the file i've on my machine.
+<code bash>
+�^?
+</code>
+which translate to //''$'\250\177'// <br>
+So check or list all the files with ascii in it.
+<code bash>
+ls [^[:ascii:]]*
+</code>
+now to remove
+<code bash>
+rm [^[:ascii:]]*
+</code>
+:!: Regex can be modified to list all matching file before removal.
