LyX ⇒ Problem with .bib file compilation in lyx

[hooman]

Hi,

I have problems running my .bib file with a few of my references such as this one:

@article{rodríguez2002arbitrary,
title={{Arbitrary Lagrangian-Eulerian (ALE) formulation for hyperelastoplasticity}},
author={Rodríguez-Ferran, A. and Pérez-Foguet, A. and Huerta, A.},
journal={International Journal for Numerical Methods in Engineering},
volume={53},
number={8},
pages={1831--1851},
year={2002},
publisher={John Wiley \& Sons}
}

I'm using a numbered order and when I run the file the number does not appear in the square brackets as shown below:

[] A. Rodríguez-Ferran, A. Pérez-Foguet, and A. Huerta. Arbitrary Lagrangian-Eulerian
(ALE) formulation for hyperelastoplasticity. International Journal for Numerical Methods
in Engineering, 53(8):1831–1851, 2002.

I think the problem is with symbols such as : é

Many Thanks in advance.

The solution is not to use the special symbols in the title or the name that you give to your reference.
