Conflict between packages utf8 and cite

I'm trying to write a project to my qualify exam and when I use the packages utf8 and cite to group references ([1,2,3]->[1-3]), it appears the follow message in the log file -

! Package inputenc Error: Unicode char \u8: not set up for use with LaTeX.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
...

l.33 \usepackage{cite}

• That is not the source of the conflict. It is probably due to an unexpected character in your .bib file that is causing BibTeX to choke. But what is \input{Bibliography.tex}? That seems like a highly unorthodox way to construct a bibliography. – jon Nov 23 '16 at 4:26
• Welcome! Do you use everything in that preamble? – cfr Nov 23 '16 at 4:31

There is a nother character (probably invisible) after \usepackage{cite}. When I copied the MWE from the question, my editor showed the replacement character U+FEFF. Delete the line and retype the line to get rid of that character.
