Note that the QOD query will return 139 characters if it runs on a database with the Latin1_General_CI_AS (or similar) collation. When running on a database with another collation, the results may vary. For example, for a Vietnamese_CI_AS database the query returns 131 characters, for a Cyrillic_General_CS_AS database – 158 characters, for a Japanese_CI_AS_KS_WS database – 122 characters, for a SQL_EBCDIC273_CP1_CS_AS (?!) database – 15 characters. But the answer given is correct though.
