U+FB01 is an fi ligature which should never be in your source file. So best would be to edit the input and replace it by fi but failing that

\DeclareUnicodeCharacter{FB01}{fi}

should work.

(Just thought I'd mention) I've encountered f-ligatures in source code from time to time. I think it's usually the result of the author copy and pasting from another source (such as a PDF created by TeX). – Nicola Talbot Feb 28 '18 at 19:25
Exactly! This was the case! @Nicola Talbot – Always learning Mar 01 '18 at 09:17
