While the proposed patch appears reasonable, I can't reproduce this bug. You should attach the file you are using and specify any non-standard settings. The image shows larger than normal characters so it appears you have changed the system scale factor.

Specified behavior is also reproduced with 100% scaling factor.
Please do the following:

1. Run Sc446.exe (www.scintilla.org)
2. Open SciTest.txt (raw.githubusercontent.com)
3. Select Main Menu-> File-> Encoding-> UTF-8
4. Select Main Menu-> Options-> Wrap
5. Press Alt+End, note behavior

How do I extract that change as a .patch file?
