Hi, I'm trying to understand if a regular expression I've designed is working correctly. It seems that I can make the regular expression match work "off by one" character in certain circumstances. For instance: The pattern: ".{1,3}" finds 1 to 3 characters, however The pattern: ".[^b]{1,3}" finds 1 to 4 characters...? For some reason when I apply a "do not allow the character b" or any other bracket operator the {min,max} range value seems to allow for one additional character. I cannot imagine this being done on purpose. The work around is to allow one less then you really want (i.e. {1,2}) but I figured I'd post something and see if anyone has seen it or could explain what is happening. Maybe its just a bug. The code example: boost::wregex pattern( TEXT( ".{1,3}" ) ); boost::wcmatch matchResults; if( boost::regex_match( TEXT( "asd" ), matchResults, pattern ) ) { // Match } else { // No match } } catch( runtime_error &e ) { printf( "\n%%FAILURE: Regular expression error: %s.\n", e.what() ); } Yes, I'm running in a UTF-16 build environment in Microsoft Windows .NET using C++. If this isn't the correct venue for this message, sorry in advance. Thanks, Derrick
