ISSUE:       6013
TITLE:       Date-time parsing is very weak
DESCRIPTION:
    Parser changed in:
    https://github.com/FirebirdSQL/firebird/commit/ff37d445ce844f991242b1e2c1f96b80a5d1636d
    See also:
        - CORE-6427 - Whitespace as date separator causes conversion error.
        - CORE-6429 - Timezone offset in timestamp/time literal and CAST should follow SQL standard syntax only.
JIRA:        CORE-5750
FBTEST:      bugs.core_5750
NOTES:
    [03.06.2023] pzotov
    If source string contains binary characters (e.g. '2001
') then it will not be converted to date,
    but content of error message depends on FB version:
        * on FB 4.x and FB 5.x prior 5.0.0.1058 it will look without changes, i.e. "2001
";
        * on 5.0.0.1058 it will look like this: conversion error from string "2029\x01\x19";
        * on 5.0.0.1066 it will look like this: conversion error from string "2029#x01#x19";
    Error text became differ after 30-may-2023:
        https://github.com/FirebirdSQL/firebird/commit/fa6f9196f9015d0cf8c1cb84ff6312934855e9e9
        ("Fixed #7599: Conversion of text with '\0' to DECFLOAT without errors")
    Expected STDERR was adjusted to current output after discuss with Alex.
    Checked on 5.0.0.1066, 4.0.3.2948.
