Known issues

When typing or pasting characters not available in the specified font, they will appear as empty squares for Windows versions below 10.

When using spellchecking, the Editbox switches to a custom undo/redo stack. It is not as intelligent as the built-in stack (it only allows undo one typed character at the time), there will be some improvements in the future.

Windows build 1809 introduced a bug causing some fonts to not work properly in the Editbox, it can be fixed for now by typing /setoption Misc UseOldRtb True. (This disables emoji support in the Editbox)

Using certain characters and certain fonts may cause the Editbox to have different characters in 2 separate fonts, this is not a bug. The windows control does this to substitute characters not available in the current font, you'll see the same thing in Notepad which uses the same control.
