Bug ID: 47690
           Summary: When DirectWrite rendering is enabled in Notepad++
                    there are still no ligatures.
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: kolan_n@mail.ru
      Distribution: ---
[Notepad++](https://github.com/notepad-plus-plus/notepad-plus-plus) is an
application based on Scintilla.
Scintilla is a library for creating textareas.
[DirectWrite](https://docs.microsoft.com/en-us/windows/win32/directwrite/direct-write-port...)
is an API for text rendering with subpixel antialiasing which can be
hardware-accelerated using Direct2D.
[SCI_SETTECHNOLOGY](https://www.scintilla.org/ScintillaDox.html#SCI_SETTECHNOLOGY)
is a enum value identifying a call to Scintilla (in fact it is done using
Windows messages).
When it is set to values > 0 (SC_TECHNOLOGY_DIRECTWRITE,
SC_TECHNOLOGY_DIRECTWRITERETAIN, or SC_TECHNOLOGY_DIRECTWRITEDC), Scintilla
uses DirectDraw accelerated via Direct2D for rendering instead of an own
surrogate.
A byproduct of enebling DirectWrite rendering is ligatures support on fonts
having them, like Fira Code. In fact it is the main reason to enable
DirectWrite in NPP.
In Windows >7 everything works fine.
In Wine there are no ligatures (and some other issues).
