Hi,  
I have a C program that uses locales set by environmet using the function setlocale(LC\_ALL,""). The locale on SLES15 is set to ja\_JP.sjis but setlocale(LC\_ALL,"") returns null.  
I’ve also checked the following:

1. Set locale to ja\_JP.sjis on SLES12 and it works fine (setlocale return ja\_JP.sjis)
2. Set locale to ja\_JP.utf8 on SLES15 and it works fine (setlocale return ja\_JP.utf8)
3. The locale setting is as follows:  
LANG=ja\_JP.sjis  
LC\_CTYPE=ja\_JP.sjis  
LC\_NUMERIC=“ja\_JP.sjis”  
LC\_TIME=“ja\_JP.sjis”  
LC\_COLLATE=“ja\_JP.sjis”  
LC\_MONETARY=“ja\_JP.sjis”  
LC\_MESSAGES=“ja\_JP.sjis”  
LC\_PAPER=“ja\_JP.sjis”  
LC\_NAME=“ja\_JP.sjis”  
LC\_ADDRESS=“ja\_JP.sjis”  
LC\_TELEPHONE=“ja\_JP.sjis”  
LC\_MEASUREMENT=“ja\_JP.sjis”  
LC\_IDENTIFICATION=“ja\_JP.sjis”  
LC\_ALL=ja\_JP.sjis

Does anybody know what cause ja\_JP.sjis locale on SLES15 doesn’t work with setlocale function, or are there any changes on locale setting for SLES15?

Thanks and best regards
