          public AggregateTranslator(CharSequenceTranslator... translators)

      Specify the translators to be used at creation time.
      Parameters:
        `translators` - CharSequenceTranslator array to aggregate

  - ### Method Detail

    - #### translate

          public int translate(CharSequence input,
                               int index,
                               Writer out)
                        throws IOException

      The first translator to consume codepoints from the input is the 'winner'. Execution stops with the number of consumed codepoints being returned. Translate a set of codepoints, represented by an int index into a CharSequence, into another set of codepoints. The number of codepoints consumed must be returned, and the only IOExceptions thrown must be from interacting with the Writer so that the top level API may reliably ignore StringWriter IOExceptions.
      Specified by:
        `translate` in class `CharSequenceTranslator`
      Parameters:
        `input` - CharSequence that is being translated
        `index` - int representing the current point of translation
        `out` - Writer to translate the text to
      Returns:
        int count of codepoints consumed
      Throws:
        `IOException` - if and only if the Writer produces an IOException
