 Hi all,
 I got another problem here while trying using boost:regex:
does boost:regex support char set substraction?
 
For example:I give boost:regex an expression"[a-z]-[d-f]".I would like the boost take the second "-" as and substracion. So this expression is supposed to be translated as
"[a-c]|[f-z]".I am wonderring whether boost:regex has such substraction symbols?
 
Thanks && Regards
 
Juan
