QT Creator editor - "replace all" doesn't when some files have UTF-8 coding

Linked to the problems caused by QTCREATORBUG-31938.

I have found that when I use the editor to do a multi-file text "Replace All" that this operation sometimes fails silently. It will have replaced text in all of the source code files except for those files that suffer from the "Error UTF-8 encoding" user prompt (i.e. files that Qt sometimes asks you to select a new encoding for and subsequent reload). 

The problem here is that you don't know it that it didn't do every file until you do a recompile and then you get lots of errors due to function names not having being changed. I suspect this is due to these non-editable files not being able to be automatically reloaded in the background by the "Replace All" operation in order to render them editable by that operation.
