Words specified as italic in title (Latex command) only appear as squares

[ladyteam]

JabRef version

5.5 (latest release)

Operating system

GNU / Linux

Details on version and operating system

Opensuse Tumbleweed

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

The simple entry example with italic used in the title:

@Article{Parlinski2021,
  author    = {Krzysztof Parlinski and Przemys{\l}aw Piekarz},
  journal   = {Journal of Raman Spectroscopy},
  title     = {\textit{Ab initio} determination of {R}aman spectra},
  year      = {2021},
  number    = {7},
  pages     = {1346--1359},
  volume    = {52},
  doi       = {10.1002/jrs.6129},
}

Will reproduce first symbols as squares. Related to issue 2784 this was fixed in Windows. What's about Linux then? I've been trying to change the font in configuration file since there is no possibility to do it in gui, but nothing changes.

Thank you in advance,
Eugene

Yeah, and I still encounter this under mac as well.

@k3KAW8Pnf7mkmdSMPHz27 Did you ever find a workaround/solution for this?
Refs #2784

[k3KAW8Pnf7mkmdSMPHz27]

Nope, I didn't look at it further. Back in #3356 (comment) it was quite easy to trigger by resizing the window.

@AEgit collected some more references in #3356 (comment)
I don't know if it is possible to do something more with handling the encoding manually, except what @LinusDietz mentioned in #2752 (comment)

[Siedlerchr]

Hm, okay, I played a it around with it, and NFC + NFD both do render squares. The other two spit out normal text.
I noticed that with css I can style the whole content in italic. So it can be displayed in theory.

[k3KAW8Pnf7mkmdSMPHz27]

Perhaps it is still the fonts? JavaFX seems to have had a lot of issues with them, and I can't replicate this issue in Ubuntu 20.4.

what happens if you change the command to title = {\\textit{Ab initio} determination of {R}aman spectra}, ?
