Fury does not preserve script/extensions following serialise/deserialise #3966
Description
Search before asking
- I had searched in the issues and found no similar issues.
Version
Fury only serialises the language/country/variant fields of a Locale, ignoring any script/extensions, resulting in an inconsistent values following deserialisation.
Component(s)
Java
Minimal reproduce step
On my machine:
Fory fory = Fory.builder().withLanguage(Language.JAVA).build();
for (Locale locale : Locale.getAvailableLocales()) {
Locale deserialised = fory.deserialize(fory.serialize(locale));
assertEquals(locale, deserialised); // This fails for locales that define a script or extensions
}
What did you expect to see?
Assertions should pass.
What did you see instead?
The assertion fails for any locale that defines a script or extensions.
Anything Else?
No response

The issue that i found is in 'LocaleSerializer.java'
private static final Map<Tuple3<String, String, String>, Locale> LOCALE_CACHE = new HashMap<>(createCacheMap());only serializes 3 fields, ignoring scripts & extensions.
LOCALE_CACHEalso uses a 'Tuple3' so it can't distinguish Locales differing in scripts and extensions.I'm working on a solution to extend the serialization to include those 2 fields.
