Fix encoding and special characters problems
Investigated problem related by ReimarBauer (RealTimeEditing2009/2009-06-27). Mobwrite's download method was truncating the inputs on ":" character. Created a test and fixed. Then, I realized unicode characters were mis-displayed. Created another test and fixed. Mobwrite don't like to work with unicode internally, so I have to do some encoding/decoding, and I has doing it wrong.
