I can't offer much help on this, but I'll share a similar experience. I have seen something like this happening on Chromium, running on Enlightenment desktop a few years ago. I recall it was affected by the scale set on the desktop 1.2:1 or something like that. I can't recall if this was also occurring on Plasma. I think I saw the same missing character problem on the title bar of the browser window. This was on English text (UTF8 encoding). Firefox and other applications didn't have a problem. At that time I recall Chromium's rendering of the menu/toolbar and window border was fighting against the desktop. Some update on Chromium eventually fixed things. So I blamed it on the interplay between the desktop, browser and graphics card/driver (radeon).
