I would guess there's a special case when the brace is the first character in the regex. `$ perl -wE 'say $]; say "Match literal" if "{,3}" =~ m<{,3}> && "x" !~ + m<{,3}>;' 5.030001 Match literal $ perl -wE 'say $]; say "Match space" if " {,3}" =~ m< {,3}> && "x" !~ + m< {,3}>;' Unescaped left brace in regex is illegal here in regex; marked by <-- +HERE in m/ { <-- HERE ,3}/ at -e line 1.` [download]	[reply] [d/l]

What's happening is that the space must be repeated. `$ perl -wE 'say $]; say "Match space" if " " =~ m< {0,3}>' 5.028002 Match space $` [download] Your error is thrown because `{,3}` is illegal as quantifier for Perl <5.34 Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]
