Hi there,

I am facing an issue with Rewired library and IL2CPP, MelonLoader is not able to load the dependency because of an invalid name:

[01:18:23.989] [DEBUG] [AssemblyVerifier] Il2CppRewired_Core.dll Has an Invalid Type Name String "MethodInfoStoreGeneric_nqXVGKvgfzozBIAcnvWAyMFzaDld_Internal_Static_Int32_IList_1_☺_Predicate_1_☺_Int32_0`1"

This is arguably a bug in Il2cppInterop which should have renamed the type to not contain those characters (so that they can be referenced in c# source code, if nothing else)

I'm not sure to understand, in C#, Unicode characters are allowed for type and method names https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/identifier-names

[EDIT] Hum... you're right, there seem to be a non-valid character in this name, but some are valid, AssemblyVerifier could take inspiration from https://github.com/microsoft/referencesource/blob/51cf7850defa8a17d815b4700b67116e3fa283c2/System/compmod/system/codedom/compiler/CodeGenerator.cs#L1926-L1968

To be clear, what I mean by invalid character is that we should, in theory, force all type and member names to contain only printable ascii characters. Whether or not you can in theory have an emoji in c# type names isn't particularly relevant because they will be a pain to type in an IDE anyway.

Submitted a PR to Il2CppInterop, hopefully it will be merged 🤞
