> When I am testing query string
> {code:java}
> "SELECT STRING(TIMESTAMP \"2008-12-25 15:30:00\", \"America/Los_Angeles\")"{code}
> on BeamZetaSqlCalcRel I found that the second string parameter to the function is unparsed to
> {code:java}
> America\/Los_Angeles{code}
> (note an extra backslash character is added).
> This breaks the ZetaSQL evaluator with error
> {code:java}
> Syntax error: Illegal escape sequence: \/{code}
> From what I can see now this character is introduced during the Calcite unparsing step.
