[Tex/LaTex] !package inputenc error unicode character ​(u+200a)


im currently writing my bachelors thesis and while inserting some cites and adding something to my bib file the above mentioned error occured. i tried to "fix" it by removing all the steps prior to the occuring error but it still remains and i just cant find any solution.
since im a total newbie in latex, i would be grateful for any quick help!
i found something that should remove this error but it doesnt:

\DeclareUnicodeCharacter{200}{„ “}

which i insert directly after


but that still doesnt solve it

thx in advance guys!

Best Answer

it is a thin space character, add

\DeclareUnicodeCharacter{200A}{!!!FIX ME!!!} 

to your preamble and then see where that text appears and retype that part of the source without the thin space character

The log file should also pinpoint the error, it will look something like

<other messages>
! Package inputenc Error: Unicode character Δ (U+0394)
(inputenc)                not set up for use with LaTeX.

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

l.766 \item \textbf{Distance $Δ$}
                                   - how much did we move by?
You may provide a definition with

which tells you that the character is on line 766 of somefile.tex
