If a backquote is in file name the index is corrupted

[pcause]

I suspect this is true for other special characters, but I had a file that somehow has a backquote {`) in it. Waypoint just used the filename and hence all the names after that in the folderindex were not clickable. Perhaps you should strip out (regex you create and allow user to voerride), or in the index you correct this by using the URL type escape (%xx) or something

You should consider not using these characters in file names. It may break more fundamental things in the future than a single plugin's functionality.
