Unix commands generally do not have problems with space characters in file names. The main exceptions are the commands that both parse their input and expand meta-characters in it. That includes mainly shell interpreters. So yes, there are a lot of issues with shell scripts and space characters in filenames. One way to overcome them has always been to use find and {}.

The question still remains: Why have I seen the "{}" problem before?
The only reasonable explanation is you have been fooled by something else, didn't double check and stayed with that believing.
Quote:
I am exploring Reborg's ideas which imply that some older shells were eating the {}. If proven, this would explain it.
Older shells were all based on the original Bourne shell. Then came the C-shell, the Korn shell and later their open source clones and more or less innovative variants. I never heard of any of them handling {} a specific way.
Quote:
I don't have access to the source code to the various editions of "find" - unlike when I was working on enhancements to RSX.
As I wrote a couple of time, the find command itself has nothing to do with it as it does receive the very same parameter whether you quote {} or not.

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 package require uri::urn ?1.1.2? uri::urn::quote url uri::urn::unquote url _________________________________________________________________ DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to handle urls using the urn scheme. COMMANDS
uri::urn::quote url This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its result. uri::urn::unquote url This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters, and returns the modified urls as its result. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category uri of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. KEYWORDS
