Mail::Multibyte::Chars#split

Works just like <tt>String#split</tt>, with the exception that the items in the resulting list are Chars
instances instead of String. This makes chaining methods easier.

Example:
  Mail::Multibyte.mb_chars('Café périferôl').split(/é/).map { |part| part.upcase.to_s } # => ["CAF", " P", "RIFERÔL"]
