TITLE: Inconsistent conversion of non-TEXT blobs in BLOB_APPEND
NOTES:
[22.02.2023] pzotov
1. Test makes TWO subsequent connections:
1) to write blobs in the table using charset UTF8
2) to READ that table using charset NONE.
This must be done in order to see how rules for BLOB_APPEND() datatype and charset work.
Otherwise (without reconnect with charset = NONE) BLOB_APPEND() will always return blob with charset
that equals to charset of established connection, with one exception:
"if first non-NULL argument is [var]char with charset OCTETS, then create BLOB SUB_TYPE BINARY"
(rules for BLOB_APPEND() result have been discussed in the fb-devel, 14.08.2022 ... 16.08.2022).

2. Non-ascii characters are used intentionally. But they all present in both UTF8 and ISO8859_1 charsets.

3. Statement 'select blob_append(<list of nuls>) from test' currently does not show <null> literal.
This is a bug and must/will be fixed. After that, test will be adjusted.

Thanks to Vlad for suggestions. Discussed 20-21 feb 2023.
Checked on 5.0.0.958.

Added 'set blob all' because result of blob_append(null, null) must be visible as literal '<null>'.
Added substitution for suppressing 'Nullable' flags in the SQLDA output: it is sufficient for this test
to check only datatypes of result.
Discussed with Vlad, letters 02-mar-2023 16:01 and 03-mar-2023 14:43.

[14.12.2023] pzotov
Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
