SH - Alternative à printf du mksh Android ? -Débordement de pile

I'm writing a shell script to be run on Android's mksh. In Bash, I can do the following:

printf -v NUMBER "%d" \'"$CHARACTER"

The command above converts $CHARACTER into a signed decimal NUMBER. But mksh does not support printf. Is there an alternative solution that just use mksh / ksh's internal commands?
