# Mathematica inserts extra \left and \right for absolute values in LaTeX output

Type the following in a Mathematica DisplayFormula cell(other styles may also encounter this problem): Esc+l+|+Esc and Esc+r+|+Esc, and save as LaTeX.

## Note: See the difference of the character between | |.

$z$ and $z_1$, $|z|$, $|z_1|$

Cell[BoxData[
\end{document}


What should I do to get valid output that LaTeX will accept?
