does it work with wchar_t?

I am getting an error with wchar_t. I also included #include <stddef.h> to bypass clang error but I do get following

PANIC: [Panic] String cannot be of zero length. (Parameter 'oldValue')
   at System.String.Replace(String oldValue, String newValue)

a special mode

Sure, it could be an option that starts at the cs program level:

Consider the case where a C library uses C strings (char*) for identifiers that are most likely less than 25 characters in length. E.g. “PlayerEntity”, “WeaponComponent”, “RenderingSystem”, etc. These strings are used frequently and usually out of context to the global C functions as part of the API to do something significant such as getting an entity or updating a component, etc, and then returning a callback. I do not want the garbage collector in C# to allocate memory in heap 0 for these strings from the callback. Instead I rather run a quick hash over the C string and use a hashtable to know if that C string’s contents has already has an analogous memory allocated in the GC and use that reference instead.

System.String.Intern(string str) would work if it accepted a raw pointer to a C style string. Otherwise, it accepts a string as input but that string instance still has to be allocated first which is not great. Also, according to the docs the memory would be retained until the application exits or restarts which is not great either.
