JSON Parse Error in European Languages

[sseiichi]

Describe the bug
When the browser language is set to a European language such as French or German, the following error occurs on page load:

SyntaxError: Expected double-quoted property name in JSON at positon 334 (line 8 column 37)

It seems that parsing the JSON string fails due to the influence of the language settings.
This issue occurs in the WebXR Export sample scene.

To Reproduce
Steps to reproduce the behavior:

1. Build the WebXR Interactions sample scene (for example, the WebXRInteractionToolkit scene).
2. Set Chrome’s language to French (or another European language) and load the page.

Unity info (please complete the following information):

• Editor version: 2022.3.62f1
• WebXR package version: 0.22.1
• WebXR Interactions version: 0.22.0
• Git or OpenUPM: OpenUPM
• Using old components (like the Desert sample) or Input System + XR Interaction Toolkit: not sure.
• Built-in render pipeline or URP: URP

Desktop (please complete the following information):

• OS + Version: Windows 10
• Browser: Chrome

Headset (please complete the following information):
It occurs as soon as the page is loaded in the browser.

And it doesn't happen to you with EN or EN-US/UK browser?

[De-Panther]

Can you add in what file this error? When opening the console log it should display this

[sseiichi]

It doesn’t happen with English, Japanese, Korean, Traditional Chinese, Simplified Chinese, or other non-European languages I can’t read.
Reproducing the log might take a few days. I’ll update once I have it.

Can you also test https://immersive-web.github.io/webxr-samples/controller-state.html ?

[sseiichi]

Got it, I’ll check it out.

Here’s a screenshot of the log when I built the WebXRInteractionToolkit scene for WebGL and loaded it in Chrome with the language set to French. This error doesn't occur when the language is set to English or Japanese.

I also tried loading https://immersive-web.github.io/webxr-samples/controller-state.html with Chrome's language set to French, but no errors occurred and the room was displayed.

Do you know which chrome version?
Which type of French?
I tried to set Chrome to "French" and "French (France)" and didn't get the error.
Does it happen in any of the samples in the repo?

Like this one https://de-panther.github.io/unity-webxr-export/Build/ ?

Ok, I guess it's related to this line

unity-webxr-export/Packages/webxr/Runtime/XRPlugin/WebXRSettings.cs

Line 95 in cf55c71

""FramebufferScaleFactor"": {FramebufferScaleFactor}

The default FramebufferScaleFactor is 1, so there's no issue in different number schemes, but I guess that if it's not the default value, and it has something like 0.5 in European scheme it might be 0,5.
So I need to make sure numbers in the settings are formatted with . instead of ,.

But this is only a guess, I'll try to build something with non default values.
If you can send a screenshot of the same experience but with English chrome, and the object values after Got WebXRSettings, that would help to confirm the issue.
