Non-Printable Characters

Does anyone have an efficient way to eliminate non-printable characters from a file? I've used methods such as DECTPU to search and eliminate ascii characters between (1-31) and (127-255) but this slows down on large files.

Bas,
I haven't used TPU in that context, but I have done similar things with TECO.
The key to efficiency is processing each character exactly once. Done properly, TECO provides a reasonably efficient way to do this.
