First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.
Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.
Last but not least you have to add the abbreviation fields to the entries.

Just type in the name using UTF-8 characters:
\begin{filecontents*}{\jobname.bib}
@article{test,
author={Ranňik, Jkří},
title={Title},
journal={Journal},

Best Answer
The evil characters still reside in the
.bblfile (which is read by TeX when it prints the bibliography) even after the.bibwas updated. A Biber run is required for these changes to propagate to the.bbl.The Biber run, however, can only succeed if the
.bcffile (whichbiblatexuses to communicate with Biber) is well-formed. If the LaTeX run had to be aborted due to an error, often the.bcfis malformed.This can leave you in a vicious circle of malformed files. (The handling of those has changed recently, so you might be fine after a few runs if you plough on ignoring the errors).
To make sure the problem does not appear you have to remove the
.bbland.bcffiles and recompile.In ShareLaTeX just press the Logs & Other Files button next to Recompile and then the little dustbin at the bottom of the rightmost pane, you will be asked to confirm that you want to delete the temporary files. See also Obtaining .bbl file from sharelatex output
