You don't really need to, TBH. I pretty much always wrote a malloc-memory `sprintf` alternative if the system didn't have one. it's only a few lines of code, that'll take maybe 10m of your day the first time you realise `sprintf` on the platform doesn't exist.
I know, that is what I was planning on doing. (and might be what I end up doing anyway since I need to truncate the utf-8 string if it is > 1024 bytes...) Still it is nice to have other options - this code is run in some tight loops so I will be profiling all the options.
