Hi,

I can't input Unicode characters in KDE apps/Qt5 apps. This worked a few days ago and suddenly stopped working, but I can't put my finger on a possible cause. I upgraded a minor version of Plasma 5, that can hardly be the problem. Also Qt5 is affected, so this isn't purely a KDE problem. I still hope you guys can help me. The small number of GTK+ applications I have installed work flawlessly, even the terminal windows of yakuake/konsole have no trouble. But kate, dolphin, kmail as well as Otter (among others) don't. It doesn't even matter whether I input them via Alt+Shift+U or via a modified xkb layout. My standard font (noto) doesn't support the characters in question (duodecimal ten (↊) and eleven(↋)), but in all other apps they are simply displayed in a font that does support them (symbola) or at least as boxes/blanks. In KDE apps nothing appears at all. There are several related results when I search, but they are mostly old and appear to be related to missing features. As I mentioned, this worked a few days ago, so there should be an easy fix.

Thanks,
Malte

edit: copy paste is no problem, they appear in symbola. Other characters cannot be typed that way either.

So it appears that via xkb unicode in general works in Qt5, but not with the characters ↊ and ↋. Possibly only characters present in the font work? That would be weird though. Input via Strg+shift works in all applications, except Qt5 applications.

So I've tried a few things and I think the reason Qt won't display those characters is because they are not part of Unicode yet on my computer. fcitx, which is what I am supposed to be using to input Unicode characters into Qt applications, does not come up with anything when I type the code. For other characters, it displays the corresponding characters as well as it's name/description (which should be TURNED DIGIT TWO and TURNED DIGIT THREE. So I suppose fcitx is looking them up in some list. I tried upgrading icu, but that isn't helping. I don't know of any other library that I could try upgrading. Does any of you have an idea?

It seems every Qt version includes a particular version of unicode and only accepts characters available in that version. An upgrade to 5.6 fixed the problem for me.
