Acentos no h:outputlink

Front-end
#1

Pessaoal,

Estou com problemas para gerar links, cujo caminho contem caracteres especiais.
Ex: \192.168.0.17\Imagens\2009\EXPORTAÇÃO\35\EXA 0017-09.tif

o comando h:outputText imprime normalmente, porém, o comando h:outputLink não funciona. O link fica assim:
file://192.168.0.17/Imagens/2009/EXPORTA%25C7%25C3O/35/EXA+0017-09.tif

Segue o codigo do xhtml:

Desde já agradeço pela ajuda!
