[icu-design] Proposal for public PunyCode class

[Mark D. <mar...@ic...>]

I propose that we make the PunyCode class public, since it is useful for
more than IDN. There are just two public methods:

    /**

     * Converts Punycode to Unicode.

     * The Unicode string will be at most as long as the Punycode string.

     *

     * @param src

     * @param caseFlags

     * @return

     * @throws ParseException

     * @draft

     */


    /**

     * Converts Unicode to Punycode.

     * The input string must not contain single, unpaired surrogates.

     * The output will be represented as an array of ASCII code points.

     *

     * @param src

     * @param caseFlags

     * @return

     * @throws ParseException

     * @draft

     */

    public static StringBuffer encode(StringBuffer src, boolean[] caseFlags)
throws StringPrepParseException{
