[WIP] equivset: add some more confusable characters
- equal vertical (|) bar to lowercase el (l)
- equal lowercase el (l) to uppercase ai (I)
Characters are confusable and have been abused.
NOTE: I cannot get the GenerateEquivset.php to work yet, so WIP until I
find a way to do so or someone is kind enough to run the script for me.
