[Xubuntu] Dead keys don’t work

[Igetin]

Expected behaviour

The according symbol should appear when a dead key is pressed twice. A modified letter should also appear if a dead key is pressed once, followed by a press of a letter key. For example, pressing the dead key with the ^ modifier and then pressing the a key should output the symbol â.

This is a fresh installation of QOwnNotes. I’m using a Finnish keyboard layout. The dead keys work properly in all of my other programs.

Actual behaviour

Whenever I try to input a symbol or a modified letter using a dead key, nothing happens.

Steps to reproduce

1. Focus any field
2. Press any dead key and then press a (compatible) letter key that you want to modify
   • Or alternatively, press the dead key twice to input the symbol itself

QOwnNotes is using a QPlainTextEdit for editing notes, do you have by chance a similar problem with other Qt applications that are using a QTextEdit or QPlainTextEdit?

â works for me on KDE Neon with German keyboard

Hmm, Telegram Desktop seems to use QTextEdit, and the dead keys work just fine there.

I just tried a couple of more Qt programs and encountered the same issue in these:

• MusicBrainz Picard 2.1.3 (Qt 5.9.5)
• qBittorrent 4.1.6 (Qt 5.9.5)

So it seems to be a Qt problem indeed, not sure how Telegram Desktop handles it. On the Qt bug tracker, there are a bunch of issues on dead keys, but I couldn’t find anything related to fcitx.

I'm not sure if they are using QTextEdit, haven't found a lot of them in https://github.com/telegramdesktop/tdesktop/search?q=qtextedit&unscoped_q=qtextedit
