Bibtex entry with unique double quotation mark causes error

[vandalt]

Hello,

I have a few bibtex entries with unique double quotation marks (") in the abstract or title (I included an example below in case it helps). They seem to cause an error: opening the .bib file shows the "Expecting a curly bracket" at the end and in the .tex file the autocomplete does not suggest anything after this entry. I don't know if they are supposed to be escaped technically, but I noticed that Overleaf and the LaTeX Workshop VSCode plugin worked fine with them not being escaped. The obvious fix is for me to fix them manually (which I did), but it can be annoying with large, automatically generated bib files (from Zotero, for example), and the error can be confusing so I thought it was still good to open an issue.

Thank you!

  abstract = {The Fine Guidance Sensor (FGS) is one of the four science instruments on board the James Webb Space Telescope (JWST). FGS features two modules: an infrared camera dedicated to fine guiding of the observatory and a science camera module, the Near-Infrared Imager and Slitless Spectrograph (NIRISS) covering the wavelength range between 0.7 and 5.0 {$\mu$}m with a field of view of 2.2' X 2.2'. NIRISS has four observing modes: 1) broadband imaging featuring seven of the eight NIRCam broadband filters, 2) wide-field slitless spectroscopy at a resolving power of rv150 between 1 and 2.5 {$\mu$}m, 3) single-object cross-dispersed slitless spectroscopy enabling simultaneous wavelength coverage between 0. 7 and 2.5 {$\mu$}m at Rrv660, a mode optimized for transit spectroscopy of relatively bright (J {$>$} 7) stars and, 4) sparse aperture interferometric imaging between 3.8 and 4.8 {$\mu$}m enabling high\- contrast ("' 10-4) imaging of M {$<$} 8 point sources at angular separations between 70 and 500 milliarcsec. This paper presents an overview of the FGS/NIRISS design with a focus on the scientific capabilities and performance offered by NIRISS.},

@vandalt Thanks for the report. There was indeed an error in the parser. Now, it should match the behavior of BibTeX (d3def46706fd2ff407b9bf58182c729737dfdc39).

Thanks for the quick fix! It does work on the file I used to report the error now
