guaranteed processing of directory trees?

["Sam Smith" <spmskr@hotmail.com>]

I can't find a standard version of the ftw thingie in ksh.

I did find some snippets of code to process a directory tree, using

(run/strings* (find ...))

But I don't know if this guarantees the processing of all files, 
directories, symlinks, etc ..., even with spaces, quotes, weird euro or 
Asian characters, and so forth.

Does anyone have a snippet that shows how to do that?

TIA.

PS as a Scsh newbie, I hope I don't ask too many stupid questions.
