Which KDE Application is producing “smart quotes” ?
Look closely at the quotes above – they’re typographically correct quotes produced by <AltGr+B> and <AltGr+N> on my German language Cherry CyMotion Linux keyboard.
I’ve now seen that, in LibreOffice Writer, “simple” quotes are automatically changed to typographically correct quotes for my Locale – “de-DE” –
Why on earth the Redmond folks coined the term “Smart Quotes” is beyond the capabilities of my failing grey cells …
If, I’m writing a document for print or wherever – the Web for example – then, any quotes should be typographically correct …
Which is why people such Donald Knuth wrote the application to provide typographical correctness. The program LaTeX is the easier to use variant.
Programs such as RUNOFF, nroff, troff and groff also provide this capability.
Therefore, I’m actually pleasantly surprised that, LibreOffice automagically performs this function for typed documents.
Sorry but, given your screenshot, Kate could be the culprit but, I can’t make it behave as you described – been through all the Kate settings – nothing found …
Could it be that, you’ve enabled something like the Kate module for “LaTeX completion”?
The symbols you are seeing are not “smart whatever”. When you type twice they aregraphical accentuation. The same type of graphical mark that you use over letter a, e.g: “onestà”.
I don’t know Italian, but some languages use “ü, é” and many others.
