damccorm opened a new issue, #19981: URL: https://github.com/apache/beam/issues/19981
When unprasing literal strings we need to escape special symbols (ex: `\n`, `\r`, `\u0012`). ZetaSQL supports for some 4-byte (or 8 hex digit) unicode via `\Uhhhhhhhh`. As of [now]([https://github.com/apache/beam/blob/8a35f408f640d04c38ad6e2a497d30410b3bff32/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/meta/provider/bigquery/BeamSqlUnparseContext.java#L59)] only 2-byte (or 4 hex digit) unicode is supported by escaping it via `\u`. More about escape sequences here (need to scroll down a little): https://cloud.google.com/bigquery/docs/reference/standard-sql/lexical Imported from Jira [BEAM-9180](https://issues.apache.org/jira/browse/BEAM-9180).
