Deprecation warning with Rails 8.1

[pablobm]

Ruby on Rails 8.1 is showing deprecation warnings, coming from this gem, when rendering check boxes. These read as follows:

DEPRECATION WARNING: String#mb_chars is deprecated and will be removed in Rails 8.2. Use normal string methods instead. (called from $path1 at $path2)
DEPRECATION WARNING: ActiveSupport::Multibyte::Chars is deprecated and will be removed in Rails 8.2. Use normal string methods instead. (called from $path1 at $path2)

The issue appears to be solved in master, as the offending #mb_chars call was removed at #747

Would it be possible to have a new version release? 🙂
