  In the text fields it is now easier to write compounds. E.g. if you try to type "cảmơn" it does not become "camởn" as before. I had to hack into the awsome vietUni.js by nthachus.
• 11/27/2013 - New Languages
  The website is now available with interfaces in Vietnamese and German. Additionally the Vietnamese interface exists in Latin script and in Nom-Script. Despite these changes the main language will remain English.
• 11/27/2013 - Levels introduced
  As the number of characters on this site has increased I have introduced a level system. So the level pages are now smaller and load faster than the previous character index.
• 11/24/2013 - New Frequency Data
  I have updated and improved the Frequency Data. The most frequent word is now "吧 và" and not "羅 là" as before. Some homonyms have been resolved to different frequencies instead of the same frequency for all characters with the same pronounciation. The frequency data is based on news articles of Vietnamese websites.
