Hello. I'm maintaining a cross-platform dialog library, and it uses KDialog under the hood. I encountered a problem about the markup language.

When it was two or thee years ago (in Ubuntu 20.04), kdialog (version 19.12) supports some XML entity escape like HTML, such as   (space), & (&), " ("), ' ('), and so on.



However, it is found that in recent versions of KDialog, some entity are not supported anymore, while some still work.





I cannot find any KDE documentation that describes this change. When I tried figuring it out from the source code, I found that the code related to displaying text in the dialogs have never changed for years. Git blame shows this:

• The text preprocessing function in KDialog - https://github.com/KDE/kdialog/blame/ma ... ls.cpp#L46
• KDialog sends the text to KMessageBox under the hood - https://github.com/KDE/kdialog/blame/ma ... g.cpp#L515
• KMessageBox sends the text to QLabel to display them - https://github.com/KDE/kwidgetsaddons/b ... x.cpp#L219

Coule anyone tell me which version did this change happen, and what has been changed exactly?
