AFAICT, there are indeed cases where using decode-coding-string instead of string-to-multibyte is not really an option, but that means "obsolete" is not really a good description. Using with-no-warnings to mask obsolescence warnings is OK when we know that the code is only kept for backward compatibility, but when there is no good replacement, it's not a good solution. So we should strive to provide valid alternatives for every use of string-to-multibyte (or de-obsolete it, tho it's not my favorite solution). Stefan
