     :alt: Coverage
 
 This package was created because at my work, `Language and Translation Technology Team`_ at the University of Ghent, we often create demos on the web that allow the user to input and process text or files. These texts are then processed by other scripts that expect clean UTF-8-texts.
-This library extends the Django FileField, CharField and TextField by checking if the content of a submitted file or text is clean UTF-8. If not, it generates an error. Extra checks are executed for four byte long characters and NULL characters.
