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

       page_util_quote - page character quoting utilities

SYNOPSIS

       package require page::util::quote  ?0.1?

       package require snit

       ::page::util::quote::unquote char

       ::page::util::quote::quote'tcl char

       ::page::util::quote::quote'tclstr char

       ::page::util::quote::quote'tclcom char

_________________________________________________________________

DESCRIPTION

       This package provides a few utility commands to convert characters into various forms.

API

       ::page::util::quote::unquote char
	      A  character,  as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
	      their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the  result
	      of the command.

       ::page::util::quote::quote'tcl char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
	      regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.

       ::page::util::quote::quote'tclstr char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl  parser  and
	      will generate a human readable representation of the character in question.  The string is returned as the result of this command.

	      The  string  does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
	      with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.

       ::page::util::quote::quote'tclcom char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser  when
	      used within a Tcl comment. The string is returned as the result of this command.

       This  document,	will  undoubtedly  contain  bugs  and  other  problems.  Please report such in the category page of the Tcllib SF Trackers
