Filtering music with non-alphabet characters (word boundaries issue)

So while I’ve been loving the smart playlists in Plex, the word boundaries (discussed previously here) in the filters cause some rather annoying issues.
I’ve been wanting to create some playlists excluding Karaoke and Instrumental versions of songs.
However, simply creating a filter with “Does not contain Karaoke” doesn’t really do anything, because of the way titles are tagged.
Those will often include “(Karaoke)”, “-Karaoke-”, “~Karaoke~”, and so on.
Example, using a song called “edge”:

I’m hoping someone can come up with a fix, or at least a work-around that doesn’t require me to include the words “Karaoke” and “Instrumental” with tons of different prefixes in these filters…
