I see a square here, and I can’t tell whether this is intended. It seems as if you wanted U+1cbc, which is currently unassigned by the unicode standard.
So if you expect anything else than a generic fallback character, please tell us what exactly you expect, and perhaps also give some hints on which font should contain the expected glyph. Perhaps provide screenshots of the expectations even and of what you actually see.
Yeah, thats as well just a replacement character. My ultimate fallback uses a square, yours a labeled square. Though the label confirms, that this symbol has no glyph assigned. Showing a replacement character is correct behaviout.
So please answer the remainder of my question, what do you expect to see instead?
