Snowflake - Escape character parameter not working in Copy statement - snowflake-cloud-data-platform

Question

Problem Statement -
While doing the data load using the copy command and by defining the escape property the statement is not eliminating the escape character from the data.
Ex-
I'm trying to load the data from the CSV file. The file is having the data in the following Format in one of the column ('EC F&G BREWER\'S INT\'L BEER'). The expectation on this is that the escape character in the data (which is backslash '\') should be removed from the data field after the load.
Following is the copy statement I'm using -
COPY INTO SANDBOX.TEST_SBX.TEST_20200512
FROM #STAGE_NAME/TEST_FILE/
FILE_FORMAT = (FIELD_DELIMITER = ','
RECORD_DELIMITER = '\n'
SKIP_HEADER = 0
FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE
ESCAPE ='\134'
ESCAPE_UNENCLOSED_FIELD='\134'
ERROR_ON_COLUMN_COUNT_MISMATCH = FALSE
DATE_FORMAT = 'AUTO' TIMESTAMP_FORMAT = 'AUTO' NULL_IF = ('NULL', 'null', '') )
PATTERN='.*.gz.*'
PURGE=FALSE
ON_ERROR = ABORT_STATEMENT
FORCE = FALSE
RETURN_FAILED_ONLY = FALSE
;
There are many columns in this file that have the () backslash in the character field, and all are getting ignored during the load.
I cannot switch to the manual column selection mode and use the Regexp to replace the escape character, I have to use the copy command without switching to the column selection mode.
I expected that the escape character configured in the file format is treated appropriately (escaped) without having to treat it as a transformation similar to how it is treated as escape characters in the other data processing/loading engines.
Please suggest what I can do here on this.

Answer 1

This is the code I have implemented
--Data File
'EC F&G ANSHUL\'s Public COMPANY'
'YB MARTHA\'S VINEYARD LOUNGE'
'EC F&G BREWER\'S INT\'L BEER'
COPY INTO test_so FROM #file_format_stage/Test_File.csv.gz
FILE_FORMAT = (FIELD_DELIMITER = ',' RECORD_DELIMITER = '\n'
SKIP_HEADER = 1 FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE
ESCAPE ='\\'
--ESCAPE_UNENCLOSED_FIELD=NONE
NULL_IF = ('NULL', 'null', '')
SKIP_BYTE_ORDER_MARK = False)
force=true
;
And the result

Answer 2

I tried replicating exactly the same still not getting the same result. Got the understanding there is problem with the file . Or something wrong at the account level parameters which is cause the problem.
CREATE OR REPLACE TABLE SANDBOX.AAGRA018_SBX.TEXT_FILE_TST
(COL1 VARCHAR(50)
);
TRUNCATE TABLE SANDBOX.AAGRA018_SBX.TEXT_FILE_TST;
COPY INTO SANDBOX.AAGRA018_SBX.TEXT_FILE_TST
FROM #~/Test_File.txt.gz
FILE_FORMAT = (FIELD_DELIMITER = ',' RECORD_DELIMITER = '\n'
SKIP_HEADER = 0 FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE ESCAPE ='\\' --ESCAPE_UNENCLOSED_FIELD='\134'
NULL_IF = ('NULL', 'null', '')
)
force=true;
select * from SANDBOX.AAGRA018_SBX.TEXT_FILE_TST;
Data File -
YB MARTHA\'S VINEYARD LOUNGE
EC F&G BREWER\'S INT\'L BEER
This is not giving the desired result
