Makes sense, sounds like that would solve it.
Yeah, I noticed that there was a built-in ScriptableObject called "comma", and I know there's a note somewhere in the documentation about using special names for certain chars. I was actually able to create a ScriptableObject named "，", so I guess it's not an invalid filename? But either way, I think the second issue about the spaces would have prevented it from working regardless.
Hope you can get it fixed, because I think this problem would apply to any language that doesn't have spaces (so at least Chinese and Japanese).
