The %.*s is very handy to print strings where you have a length, but there is no NUL termination. It's quite widely supported but at least one vendor RTOS toolchain doesn't have it. Since there aren't that many uses of it yet, audit all uses and convert to a new helper lws_strnncpy() which uses the smaller of two lengths.
