scp_replace_strange_chars not working with Japanese Chinese characters

Hi Experts,

We are using FM scp_replace_strange_chars to replace invalid characters from BSEG-SGTXT field while loading in BW. With default setting the FM works fine and removes invalid characters however converts Japanese & Chinese characters to dots.

By maintaining parameters INTER_CP as 4103, text appears as expected but in this case invalid characters are not removed from text.

Please let me know how to handle both invalid characters and keep text intact using this FM or any other alternative. Ours is a Unicode system.

Thanks.
