Your character converts to char DBB8. According to the standard,
characters in the range D800-DFFF are not characters but surrogates.
They don't mean anything by themselves and are thus rejected by
postgres.

This character should be preceded by a low surrogate (D800-DBFF). You
should combine the two into a single 4-byte UTF-8 character.

Have a nice day,
