class Mail::Multibyte::Chars

Passing +true+ will forcibly tidy all bytes, assuming that the string's encoding is entirely CP1252 or ISO-8859-1.

Replaces all ISO-8859-1 or CP1252 characters by their UTF-8 equivalent resulting in a valid UTF-8 string.

def tidy_bytes(force = false)
  chars(Unicode.tidy_bytes(@wrapped_string, force))
