Accept player names that look right and cannot fake someone else

Players type names with invisible characters, text that flips direction, a hundred spaces, or the same name as a friend with a different capital letter. All of it ends up confusing the scoreboard and the chat. Here is a cleaner that handles the odd cases and a way to give duplicates a number.

Why this works

A name is something other people read and trust. Stripping what cannot be seen, and treating look-alikes as the same, makes the name on screen the name that was typed, so one person cannot pass as another.

When not to use it

Skip it in a closed game among friends who log in with real accounts, where the account already says who is who. Also, no cleaner can judge rude or hateful names; that needs a word list, a report button or a person.
