Re: ascii char 26

You're right.  I messed up, and it was the em dash.  It turned into 26
after going thru 'b = html.getBytes("US-ASCII");'

Here's the new code:

	public static String convertToAscii(String html) {
		html = html.replaceAll("\u2019", "'");
		html = html.replaceAll("\u201D", "\"");
		html = html.replaceAll("\u201C", "\"");

		// mdash
		html = html.replaceAll("\u2014", "-");


		byte[] b = null;
		try {
			b = html.getBytes("US-ASCII");

		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return html;
	}

Also, I'm on Android 2.1, so import java.text.Normalizer; doesn't
work.
