I still use Nedit, plus a recode script to convert to/from UTF-8.
Gedit is UTF-8 capable, but still a bit slow in popping up and it can't handle doubling of line by simple marking and middle-button clicking. Also I won't be surprised if it had no complete server-mode (like nedit-nc -line %l -file %f).
One day Gedit will catch up, when all the shiny icons are polished and no more bells and whistles to add.
