System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.48

Blender Version
Broken: version: 2.83.2, branch: master, commit date: 2020-07-09 05:50, hash: 239fbf7d93
Worked: unknown

Short description of error
When I use this symbol: \ in the name of custom property here it makes a problem: I can't see data of the property as you can see on the screen (IK\FK). Also, If the same symbol is in the name of constraint it also cause problem: I can't add driver to the influence of constraint. But there is no such problem in the tutorial. Also I use Bone Layers add-on, but it's also used in tutorial and there is no any problem.

Exact steps for others to reproduce the error
Just add the slash in the name.)

PS: It's not very important to me, I just deleted the \ but I guess it can be useful for you to improve Blender.)
Thank you a lot.

BTW, about my previous report: https://developer.blender.org/T78567

When I use wireframe mode Blender does not couse any problem. That's why I did not answer. Sorry for it.
It's not a good solution, but it's better than nothing.

P1533 seems to solve this partially. However, I think a better solution would be to simply forbid some characters in custom property names (like \ and "). Alternatively, instead of forbidding some characters, we could also have an allow-list instead, but that might break some files.

@mont29, what do you think. Should we forbid those characters? They don't seem to work currently anyway.

@JacquesLucke I would just create a forbidden list of characters yes… \, ', " at least I guess?

Yup, that last seems fine. We can always add more in the future if necessary.
