Twim with Unicode support

Posted on by

I added UTF-8 encoding support to the Twim application. In case you didn’t know, Twim is Twitter client software that runs on all phones that support J2ME. With the latest version you should be able to see correct characters in tweets if your phone has required fonts available. Here’s for example my test tweet containing simplified Chinese characters:

This was rather easy to implement since we can define encoding when constructing stream reader from input stream:

  1. public void doStuff(InputStream stream) {
  2.   InputStreamReader reader;
  3.   try {
  4.  
  5.     // Try to initialize reader with UTF-8 encoding
  6.     reader = new InputStreamReader(stream, "UTF-8");
  7.  
  8.   } catch (UnsupportedEncodingException ex) {
  9.  
  10.     // Device doesn’t support UTF-8, use default
  11.     reader = new InputStreamReader(stream);
  12.  
  13.   }
  14.   // …read data and do stuff…
  15. }

This version also has a new feature for refresing the feed without the need for restart. You can download the application from Phoload page or from here.

Mobile Trail Explorer v1.13 contains a new feature which is called OpenStreetMap Surveyor. With this feature all you OSM users can add common places to your OSM trails very easily. This is how you can active this feature:

  1. Choose “Keys” section from Settings menu
  2. Choose which key you want to configure, # or *
  3. Choose “Surveyor” action for selected key

Now you can activate the feature by clicking the selected key while you are recording your trail. When key is clicked you are shown a list of predefined placemarks from which you can select correct entry. This way it is quite easy to add bus stops etc. while you are walking, biking or driving around.
