For example: Origin character of (津)Tianjin: 𦘔 (Unicode+23E01 ?) [𦘔] [𦘔] gets converted to question mark after saving any edits.
Is this working as intended / not-a-bug (i.e., are those characters somehow invalid)? They show up during initial mem-generation and preview, but upon save and reload are replaced with ‘?’(question mark) symbol.
