The application encounters errors when PostgreSQL attempts to process strings containing invalid or unsupported Unicode escape sequences. This commonly occurs in applications using psycopg2 to interact with PostgreSQL databases, resulting in queries failing with \"unsupported Unicode escape sequence\" errors. The underlying issue is that PostgreSQL's string parser attempts to interpret escape sequences like '\\uXXXX' according to Unicode standards, but rejects malformed or incomplete sequences.
