Purpose: Some special characters from Unicode ‘’“”｜–—―（） look very much like ASCII to the naked eye. They should not be used in canonicals. Also, two apostrophes instead of a double-quote are bad practice. This script helps you find the canonicals that need fixing in your bins.

Instructions: Based on a tag search query that finds any canonical tags with "illegal" characters, this script trawls through each of your assigned fandoms individually. You'll only see results that YOU can fix!

1. At the top right of a blank Tag Search page, a "Check Illegal Characters" button appears.
2. Click it - the script will start checking in the background. The button's text will count down how many fandoms are still pending.
3. When it finishes, the results are displayed grouped by fandom in which they were found.

Note 1: the button only appears on an empty tag search. Once you searched for something, the button does not appear anymore to avoid clicking it by accident in the course of regular wrangling.
Note 2: Works both with a vanilla tag search, or when you have the All Buttons on All Pages script enabled - the button appears at the end of the configured buttons.
Note 3: The background checking is deliberately slow, to avoid getting rate limited. It waits for 3sec between fandoms.
