Dinamic loaded text is not bound by text box

Hello everybody.

I had my firt dinamicaly loade text box whith external txt.
I followed the "Scrolling Dynamically Loaded Text by kirupa chinnathambi

Two problems have appeared:
The text is not fitted to the textbox sise
All words whith accents “é” “à” or special caracters “Ç” apear as squares.

Anyoune on this, I could use some help on this, a client needs to have the texts renewed from time to time, and i shoul make it able for him.

Thanks a million times for any light on this matter.

PS: this happens also to swish user as I know.
