Problem Note 61197: When used under SAS® UTF-8, the KLOWCASE and KUPCASE functions return garbage characters
 |  |  |  |  |
When applying the KLOWCASE or KUPCASE functions to some national characters in a SAS UTF-8 session, you might see the unprinted or garbage characters in the results.
For example, after the code below is run, the hexadecimal code of the results are different.
data _null_;
l=klowcase('c4b0'x);
u=kupcase('c4b1'x);
put l=$hex. '(Should be 6920)';
put u=$hex. '(Should be 4920)';
run;
l=69B0 (Should be 6920)
u=49B1 (Should be 4920)
l=klowcase('c4b0'x);
u=kupcase('c4b1'x);
put l=$hex. '(Should be 6920)';
put u=$hex. '(Should be 4920)';
run;
l=69B0 (Should be 6920)
u=49B1 (Should be 4920)
To work around this issue, use PROPCASE to make the string lowercase or uppercase. Here is an example:
propcase(string,'','L');
propcase(string,'','U');
