Re: [Image] New Button Tag and Text Tag with HTML rendering capability

[Michael McGrady <mi...@michaelmcgrady.com>]

Hi, Abey,

I have been under the gun here and will get back to you on this.  For the 
moment, I thought it might be helpful to send along this code that I use to 
put i18n text into buttons.

package com.crackwillow.resource.image.button;

import java.io.*;
import java.util.*;

import com.crackwillow.log.StdOut;

public class UnicodeConverter {
   public static String convert(String unicode) {
                 try {
                         byte [] utf8Bytes = unicode.getBytes("UTF8");
                         unicode = new String(utf8Bytes,"UTF8");
                 } catch (UnsupportedEncodingException uee) {
                         log("log.error",uee.getMessage());
                 }
                 return unicode;
         }

         public static void log(String logFileName,String message) {
                 StdOut.log(logFileName,message);
         }
} ///;-) Michael McGrady

Later,

Michael
