StringArgumentType.word() doesn't support symbols

[Londiuh]

Describe the bug
Not a bug, but the StringArgumentType.word() argument used in the login and register commands doesn't support symbols. So players can't register with passwords containing symbols. Only letters, numbers, ., - and _.

StringArgumentType.string() supports symbols, but only if you put the string inside quotes, this can be annoying to players.

StringArgumentType.greedyString() supports symbols but captures everything until the end of the command. The register command will have to check if the input contains spaces, because passwords shouldn't contain spaces. Also, it won't be able to have the repeatPassword argument.

To Reproduce
Steps to reproduce the behavior:
Try to register with a password containing symbols.

Expected behavior
Passwords should be able to contain symbols.
