Accents such as \"{\i} in bib fields get flagged as errors

[gi1242]

Hi there,

I noticed that certain accents in .bib files get flagged as errors. Here's an example:

@Article{	  BenaimLeBorgneEA15,
  author	= {Bena\"{\i}m, Michel and Le Borgne, St\'{e}phane and
                  Malrieu, Florent and Zitt, Pierre-Andr\'{e}},
  title	= {Qualitative properties of certain piecewise deterministic
                  {M}arkov processes},
  journal	= {Ann. Inst. Henri Poincar\'{e} Probab. Stat.},
  fjournal	= {Annales de l'Institut Henri Poincar\'{e} Probabilit\'{e}s
                  et Statistiques},
  volume	= {51},
  year	= {2015},
  number	= {3},
  pages	= {1040--1075},
  issn	= {0246-0203,1778-7017},
  mrclass	= {60J99 (34A60 60J25 60J75)},
  mrnumber	= {3365972},
}

The \"{...} is getting flagged as an error by texlab, and it says:

Expecting a field value

in the diagnostics. It's of course perfectly correct latex.

Thanks in advance.
