ISSUE:       5749
TITLE:       Token unknown error on formfeed in query [CORE5479]
DESCRIPTION:
    Test makes temporary .sql file and writes there several queries like:
        select 'some_text'<DELIMITER>from rdb$database;
    - where <DELIMITER> is every character from following list:
        findstr /i /c:"CHR_WHITE," %fb_sources_home%/master/src/dsql/chars.h
    Output:
        009     CHR_WHITE,  // 0x9
        010     CHR_WHITE,  // 0xA
        012     CHR_WHITE,  // 0xC
        013     CHR_WHITE,  // 0xD
        032     CHR_WHITE,  // this can be skipped from check

    NB: character \u000B [currently] NOT present in this list.

NOTES:
    [18.02.2023] pzotov
    Confirmed problem on 5.0.0.736 (18-sep-2022): literal 0xC ('\u000c') could not be used as delimiter, got:

        -SQL error code = -104
        -Token unknown - line 1, column 15
