When using long key/user name which consist of non-ASCII characters, the key search or policy update is failing for respective key/user.
SQL command execution error: ERROR: value too long for type character varying(255)
This problem appears because PGP Universal stores non-ASCII characters in the database as textual representations of UTF-8 octets instead of UTF-8 characters. Depending on the character, a single character can be represented by up to 16 "character varying" values.
Here is an example how the 7-character Cyrillic word "Русский" (literal "Russian") is represented on the database level: "\320\240\321\203\321\201\321\201\320\272\320\270\320\271". In the example above each Cyrillic character is encoded as a 2 byte value which is stored as 8 symbols in the database.
