RegEx: case sensitivity

[jedison]

I tried a very simple RegEx (which tests fine on https://regex101.com/) and it does not really work the way one would expect on NotepadNext.
Namely "[A-Z][A-Z][a-z]"
NotepadNext does not take into account uppercase/lowercase, UNLESS I turn on "Match case" which I don't think really makes sense. In the RegEx, I have specified case... why should I have to turn on Match case? That should only apply to non-RegEx searches.
As I am on Mac now, I cannot test the same RegEx on Notepad++, but if I get the opportunity, then I will.

Notepad++ and many other popular editors (e.g. Visual Studio) also support case sensitivity when using regular expressions. So there is definitely precedence of being able to toggle regular expression case matching. This particular behavor may be reviewed though once I have time to implement a real regex engine rather than relying on the current QRegularExpression implementation
