TSQL code to remove junk characters by the aid of Number Table

Suppose we have some record mixed with special characters like

! @ # $ % ^ & * ( ) { } < >

Our objective is to remove those special characters. The below is a technique we can do so

DECLARE @NoisyData VARCHAR(MAX)
SET @NoisyData = 'hello! DNF * > This is % a (: . nice platform to learn :). Thank you so much!'

;WITH numberCTE AS
(
 SELECT 1 AS Rn
 UNION ALL
 SELECT Rn+1 FROM numberCTE WHERE Rn<LEN(@NoisyData)
)
SELECT REPLACE(FilteredData,'&#x20;',SPACE(1)) CleanedRecords 
FROM 
(SELECT SUBSTRING(@NoisyData,Rn,1) 
FROM numberCTE  
WHERE SUBSTRING(@NoisyData,Rn,1) NOT IN('!','*','>','<','%','(',')',':','!','&','@','#','$')

FOR XML PATH(''))X(FilteredData)

Result
/*
CleanedRecords
------------------

hello  DNF     This is   a    . nice platform to learn   . Thank you so much
