Yes, I need more. Is that defined as 260 bytes or 260 characters? The following paragraphs do mention Unicode normalization and storage (USC-2 probably, given Microsoft's penchant for backwards compatibility), but not how that affects the path length.

Are combining characters counted separately for MAX_PATH purposes? Do surrogate pairs count as one or two characters?

This is 2016, we really shouldn't need to be asking these byte-vs-character questions any more :(
