Description
Brief Summary
Some parts of the string sent from the BackingBean are missing only when making an AJAX request.
It appears that IVS (Ideographic Variation Sequence) characters and similar may be causing the issue.
Examples of missing characters: 𠮷,𠮟,🇯🇵,🇺🇸,🤣️
Expected Outcome
The complete string should be returned during an AJAX request, just as it is when performing a standard GET request.
Current Outcome
A string with missing characters is returned only when making an AJAX request.
In the example shown in the screenshot below, both the top and bottom rows should produce the same characters.
Reproducer
Not affected: payara-6.2024.9, payara-6.2024.10
Affected: payara-6.2024.11, payara-6.2024.12
In the following example, the BackingBean method is called from JSF via an AJAX request.
public String getSampleText() {
return "𠮷,𠮟,🇯🇵,🇺🇸,🤣️" + new Date();
}I have prepared a minimal reproducible sample for this bug and attached it.

After running it, clicking the "post ajax" button on the screen reproduces the missing characters.
