Problem solved: Notepad++ needed to be restarted after installing WinCompose. (Notepad++ obviously hooks into the keyboard handling at quite a deep level – it also needs to be restarted after changing keyboard layout.)
Sourceforge is no longer used for Notepad++. Issues for Notepad++ can be created here on Github. Also, it looks like this exact issue has already been reported.
@tomas-chrastina Thanks very much for your help! This solved my issues! Also, after trying this, I noticed that right-clicking within the text box shows a “right-to-left reading order” toggle.
Under Global Styles there is Global override and Default Style. The override only takes affect when you enable it with the checkboxes below it. Normally you will want to change the default style so you can also change it at the individual level.
If you’re trying to change a font and nothing is happening then check that the global override is not enabled.
In the UDL dialog, click the “Operators and Delimiters” tab. Under the caption “Delimiter 1” add the double quotation mark " as both “Open” and “Close”, the backslash as “Escape”. Same for the single quotation mark under “Delimiter 2”.
