[Fuzzy select] panic when writing non standard letter

[Araxeus]

It would be awesome if fuzzy search could be made to work with languages that aren't English

If that's somehow impossible, at least handle the panic?

thread 'main' panicked at 'byte index 1 is not a char boundary; it is inside 'Б' (bytes 0..2) of `Б`',
C:\Users\Araxeus\.cargo\registry\src\github.com-1ecc6299db9ec823\dialoguer-0.10.0\src\theme.rs:599:27

Examples:

• With Accent: À
• Cyrilic: Б
• Arabic: ش
• Greek: β
• Hebrew: ש
