possible issue

Hello

I want to link to a file on the Web that has square brackets in its 
name. I have escaped those characters but am still getting "Illegal 
character in path segment"

<a 
href="http://publ.lib.ru/ARCHIVES/F/FEDOTOV_Yakov_Andreevich/Fedotov_Ya.A..._Tranzistory.(1960).&#91;djv-fax&#93;.zip">Transistors</a>

Is this correct? The page looks fine in Firefox and the link works!

cheers

Andrew
