For me Konsole also doesn't show emojis and also many other characters, Chinese, are shown as question marks on a white rhombus. My bet would be on font substitution (that's the mechanism that falls back to another font if a glyph is missing from the chosen font). It just doesn't seem to be working/active in Konsole, or it's working in a very limited way.

In KMail however, also a KDE application, I have the Emojis (e.g. ๐Ÿ˜€) and any characters (e.g. ่ฏญ่จ€, where the second character wouldn't show in Konsole) just fine, even with fixed-width font.

Google doesn't bring up anything useful, or I'm using the wrong search terms, as if we were the only two people that had this issue... Maybe someone here has an idea?
