TEXTO RTF1(VB) P/ UTF-8 PHP

[Rafael Motta 0]

Boa tarde galera! Preciso de um suporte, caso alguém saiba uma forma de converter, ou conheça algum componente do php. Enfim, tenho um campo no banco de dados que salva textos(formato blob), porém ele salva em formato rtfl (provindo do sistema antigo feito em VB), precisaria de um componente ou alguma função que convertesse esses dados ao extrair do banco e jogá-lo no meu campo de texto... segue o exemplo abaixo.

Desde já, Agradeço!

{\rtf1\fbidis\ansi\ansicpg1252\deff0\deflang1046{\fonttbl{\f0\froman\fprq2\fcharset0 Times New Roman;}{\f1\fnil\fcharset0 Microsoft Sans Serif;}}
\viewkind4\uc1\pard\ltrpar\fi567\qj\f0\fs24 Bem, \'e9 que muitas pessoas n\'e3o tem esse problema, mas todos tem ao menos um cal\'e7ado em casa que causa o mau cheiro no cal\'e7ado, pois o contato da pr\'f3pria transpira\'e7\'e3o com o material de determinados cal\'e7ados causam o odor, al\'e9m disso ele proporciona um efeito refrescante, ent\'e3o \'e9 ideal para uso do dia-a-dia e para manter o cal\'e7ado sempre com cheiro agrad\'e1vel.\par

achei algo que supostamente remove as tags e "limpa" o texto do rtf, segue em anexo, porém queria que essa função filtrasse na entrada do campo de texto como na imagem (anexo 1 ). Obrigado!
