What a waste of SMS it is, when there are some characters with accents. Instead of 160 chars per SMS you only get 70. Well no more. This app will replace all the special characters and you'll get your full 160 chars back. You can also extend existing rules or create your own set of rules to replace the special accented characters. Replacing whole words is not a problem, too. Feel free to export and share your settings with anybody. Or simply import those settings back.
