经典java转码程序同native2ascii.exe

private String convert(String str) {

		String tmp;

		StringBuffer sb = new StringBuffer(1000);

		char c;

		int i, j;

		sb.setLength(0);

		for (i = 0; i < str.length(); i++) {

			c = str.charAt(i);

			if (c > 255) {

				sb.append("\\u");

				j = (c >>> 8);

				tmp = Integer.toHexString(j);

				if (tmp.length() == 1)

					sb.append("0");

				sb.append(tmp);

				j = (c & 0xFF);

				tmp = Integer.toHexString(j);

				if (tmp.length() == 1)

					sb.append("0");

				sb.append(tmp);

			} else {

				sb.append(c);

			}



		}

		return (new String(sb));
