Allow Euro '€' in code page 936 for 0x80.
Fix SCI_SETSELECTIONNSTART and SCI_SETSELECTIONNEND to behave more sensibly.
Fix lexing after undo at end of document.
When a line end is not selected, change the colour of the rectangle that indicates the line end is selected to white space background instead of previous character's background except for EOL filled style.
On Qt, add const to ScintillaDocument and ScintillaEdit methods.
On Qt, prevent crash when using ScintillaDocument object.

Change format for SCI_GETSELECTIONSERIALIZED. Feature #1563.
Ensure selection drawn correctly when selection restored by undo. Bug #2487.
Update to Unicode 16. Feature #1569.
Fix bug when indenting rectangular selection. Feature #1567.

For Win32, update Direct2D and DirectWrite interfaces used to 1.1 and add a lower-level approach to calling DirectWrite 1.1 by specifying SC_TECHNOLOGY_DIRECT_WRITE_1. Since Windows Vista does not support these API versions, Scintilla o longer supports DirectWrite on Windows Vista and will fall back to using GDI.
Fix segmentation of long lexemes to avoid breaking before modifiers like accents that must be drawn with their base letters. For wrapping, try to break lines without separating letters from modifiers.
