I want to remove all

Answer 1

If we also want to handle white spaces and unwanted tabs-

Check and Try the below script (Unit Tested)-

--Declaring
DECLARE @Tbl TABLE(col_1 VARCHAR(100));

--Test Samples
INSERT INTO @Tbl (col_1)
VALUES
('  EY     y            
Salem')
, ('  EY     P    ort       Chennai   ')
, ('  EY     Old           Park   ')
, ('  EY   ')
, ('  EY   ')
,(''),(null),('d                           
    f');

SELECT col_1 AS INPUT,
    LTRIM(RTRIM(
    REPLACE(
    REPLACE(
    REPLACE(

        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(col_1,CHAR(10),' ')
        ,CHAR(11),' ')
        ,CHAR(12),' ')
        ,CHAR(13),' ')
        ,CHAR(14),' ')
        ,CHAR(160),' ')
        ,CHAR(13)+CHAR(10),' ')
    ,CHAR(9),' ')
    ,' ',CHAR(17)+CHAR(18))
    ,CHAR(18)+CHAR(17),'')
    ,CHAR(17)+CHAR(18),' ')
    )) AS [OUTPUT]
FROM @Tbl;
