how to solve a Unicode char' (U+301) error?

Question

I have a problem within ShareLaTex. I copied a reference from biblatex and pasted it into my bib file and the ignored command is

author={Ran{\v{n}}ik, Jk{\v{r}}{\n}́}

which should generate

$not this: {Ran{\v{n}}ik, Jk{\v{r}}{\n}́}$

I get the following error message:

Unicode char' (U+301)

I add references to my bib file with ~ signs or accents.

U+0301 is a combining accent, it is best to enter accented commands as single characters or as tex markup \'{e} rather than e followed by a unicode combining acute — David Carlisle, Sep 12 '16 at 18:11

ah biblatex/biber not bibtex, you didn't say... still it's hard to debug without an example. (or even the complete error message) — David Carlisle, Sep 12 '16 at 18:43
Is the ' after the last bracket there on purpose? Isn't there a closing bracket missing at the end? — Stephen, Sep 12 '16 at 18:52
yes it is on purpose author={Ran{\v{n}}ik, Jk{\v{r}}{\n}́}, — John, Sep 12 '16 at 19:08
The ́ character is the obvious culprit. Retype the name using proper encoding. Moreover \n makes no sense. If I google for Ranňik I get nothing — egreg, Sep 12 '16 at 19:14
How can I convince biber to produce the correct unicode character for í? — John, Sep 13 '16 at 15:22
It's quite obvious that you should at least use i if you want an accented i. But if you're using biblatex, why not simply Ranňik Jkrí? — egreg, Sep 14 '16 at 18:08
Also relevant: Input encoding error after upgrading from Biber 1.9 to Biber 2.1 as well as linked questions. — moewe, Sep 15 '16 at 07:29

Just type in the name using UTF-8 characters:

\begin{filecontents*}{\jobname.bib}
@article{test,
  author={Ranňik, Jkří},
  title={Title},
  journal={Journal},
  year={2016},
}
\end{filecontents*}

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
\cite{test}
\printbibliography
\end{document}

\n is generally not defined and the ' afterwards generates the error message. About the "{\'{i}} an error occurs" from your comments: That should be \'{\i}, where \i creates an "i" without dot, so that the "´" can be placed there.

Thus author={Ran{\v{n}}ik, Kj{\v{r}}{\'{\i}}} should produce the right output.

About accents etc. you can find additional information at:

For being BibTeX compatible it should be Ran{\v{n}}ik, Kj{\v{r}}{\'{i}} – egreg Sep 14 '16 at 18:06
@egreg: Thanks, +1, fixed my answer for the missing brackets, but \i instead i also for BibTeX, or not? – Stephen Sep 14 '16 at 18:08
