regular countenance extracting calm an rtf string

i looking proceed mislay calm rtf twine i found following regex:

({\\)(.+?)(})|(\\)(.+?)(\b)

however indirect twine twin right angle brackets "}"

before: {\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 ms bombard dlg 2;}{\f1\fnil ms bombard dlg 2;}} {\colortbl ;\red0\green0\blue0;} {\*\generator msftedit 5.41.15.1507;}\viewkind4\uc1\pard\tx720\cf1\f0\fs20 u send me info pls\f1\par }
