Confirming the bug. I'm using Quanta+ 3.4.3 delivered with Ubuntu 5.10.

I uninstalled the package and built Quanta+ 3.4.2 from source to check if it could be resolved. But it didn't.

I really need this functionality for my work.

There was a bug when I wanted to restore the functionality. So you have 
to manually add the following to the local quantarc file (after you 
closed Quanta), under 
[General Options]
Replace Accented Chars=true
Replace Chars Not In Current Encoding=true

Does it work with these settings_

Thank you for your answer. I opened ~/.kde/share/config/quantarc and found where it said:
Replace Accented Chars=true
Replace Chars Not In Current Encoding=false
so I edited it to read:
Replace Accented Chars=true
Replace Chars Not In Current Encoding=true
then saved and closed. Then I opened Quanta, but it still didn't work. I then closed quanta and re-opened quantarc and found that it had been changed back to:
Replace Accented Chars=true
Replace Chars Not In Current Encoding=false
I then repeated the whole process just to be sure, and the same happened again.

Hm, in this case it might be possible that you need to wait until 3.5 
comes out or patch the source yourself. I will post the patch soon.

When is 3.5 due?

Tried same process than Jeremy in comment #3. Same (bad) result.
And so, same question: when is next version due?

Apply the following patches plus follow my previous instructions in 
order to get this working. It will work in 3.5

Thanks. As 3.5 is due within a few weeks and I have no idea how or where to apply the patches, I think I'll wait.

Thanks, Andras, this is great! 

But I'm looking on my 3.4.2 document.cpp source code and it doesn't look the same. For wich version is this patch?

The patch is for 3.4.3.
