One approach you could use is like that used by write-region: it uses
coding-system-for-write if it's non-nil, otherwise it uses
buffer-file-coding-system, and if that is nil, it calls
find-operation-coding-system, and, if that doesn't help either, it
finally uses the default value of buffer-file-coding-system.

See Fwrite_region on fileio.c, for more details.
