      I am trying to create a plugin for inserting mathematical symbols for my mathematics documentation.
      I have used the following to accomplish this:
      SendMessageW(nppData._scintillaMainHandle, SCI_REPLACESEL, NULL,(LPARAM)text)

      However, after executing this command, the entire document view is temporarily changed to ANSI, causing my newly inserted character, as well as other UTF-8 characters to display incorrectly. If I change tabs, then return back to this one, the file view is reverted back to the default UTF-8 and the characters display correctly. I have tried various approaches to fixing this such as SCI_SETCODEPAGE with SC_CP_UTF8 as well as using WM_PAINT to no avail.

      Is there a way to fix this issue?

        I have not had such a problem yet.
        Could you give us an example of the text to be inserted and a document content so that it can be understood?
        Preferably as minimal as possible.

          This seems to be an extreme route to go to, to do this.
          Curious why you would try it this way – is there some advantage?
          I agree with @Ekopalypse that some more info about your workflow would definitely help.

          Perhaps THIS THREAD is of some interest.

            I managed to solve the issue this morning after reviewing the source to the mime tools plugin.

            The following lines of code resulted in the data being displayed correctly.
            SendMessageW(nppData._scintillaMainHandle, SCI_TARGETFROMSELECTION, 0, 0);
            SendMessageW(nppData._scintillaMainHandle, SCI_REPLACETARGET, len, (LPARAM)text);

            Thank you for the assistance.
