Please provide full Unicode support (or at least up to 5.2)

What steps will reproduce the problem?
1.Text in some newer Unicode blocks in unreadable (it shows squares or question 
marks instedad of a text)
2.Even if the text do show proper signs the font constantly resets itself to 
some default ("sans" in my case). To get readable text back you are forced to 
change the font back every time which is very tiresome
4. Please make it possible to select a sign (or even a whole block of signs) 
and paste the selected sign into the text (a character map of some sort to make 
possible creating notes with less frequently used characters)
3.Btw would it be possible to change the background color for the whole page 
instead of an active line? It would make reading and writing of a longer text 
more eye friendly.

What is the expected output? What do you see instead?
To see readable text in scripts from the latest unicode ranges especially 
5.0-5.2
Akkadian and Egyptian in my case

I do the same experience the UTF-8 fr-FR isn't totally supported. "special 
characters" can not be entered (e.g. : Ø  œ  ±) and using French dvorak 
keyboard (pkl.exe) I have the same trouble. (here I can Ω, ŝ, ²³⁴⁷ the 
dead keys are working)
