#                   ascii_char(0) was allowed to be concatenated with string and pass then to cast(... as timestamp)
#                   up to 4.0.0.1227 (29-09-2018), and is forbidden since 4.0.0.1346 (17.12.2018).
#                   FB 3.x allows this character to be used and issues timestamp instead of error.
