It seems that if I try to use Unicode characters above the Basic Multilingual Plane, i.e. characters with code points higher than U+FFFF, the so-called "astral plane" characters, something odd happens. My text completely disappears. I noticed this when I attempted to type a post with the official name of Evangelion Shin Gekijouban: :||, which really should be the repeat sign in sheet music (U+1D107). The entire text of my post disappears completely. I can edit the post again, and my original text appears, and where I typed the offending character appears as five question marks inside of black diamond shapes.
