Non-printable or 'special' characters affecting Standardization

You are passing row data to the SAS Viya Data Quality Standardization transformation which contains 'special' characters.


Non-printable characters exist in the row-level data that cause Standardization to process incorrectly or fail.  Removal or recasting of the non-printable characters should solve this problem. 


You won't find me posting too many programming-related comments, but this is a simple solution that can take care of potentially repetitive faults in Standardization.  It's a re-print from an early reply on this subject that is worth showing again. 


The solution is: 

1) swap out non-printable characters with,

2) a safe character so that,

3) standardization runs properly. 


Detail, explanation, and sample code is here:


The SAS sample Note is missing the VERIFY function solution. Perhaps it should be as below :


test=verify(UPCASE(string),' !@#$%^&*,.1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ');
