Message definition (Development/Tutorials/Common Programming Mistakes)

If you are reading in a file, it is faster to convert it from the local encoding to Unicode ({{qt|QString}}) in one go, rather than line by line. This means that methods like <tt>{{qt|QIODevice}}::readAll()</tt> are often a good solution, followed by a single {{qt|QString}} instantiation.
