Modifier Acute/Grave

I'm trying to figure out what the 'Modifier Letters' are about. I've created spacing variants of grave and acute at 0060 and 00B4, and then created zero-width combining diacritics at 0300 and 0301. These latter two have anchors and I've used them to build the accented Latin glyphs from composites. Now I find there are two more codepoints called Modifier Letters at 02CA and 02CB. Who can tell me what they're for and what I should put in there?

I'd copy over 0060 and 00B4 into those Modifier Letter codepoints.

Some use of those characters was mentioned in the thread

Yeah, they’re supposed to be spacing versions of the combining diacritics as well as a few things that don’t have combining versions. So what Chris Harvey said. They should look exactly like the combining versions but should have an intrinsic width, perhaps something like a plain space (U+0020). If you have uppercase variants of diacritics you should only use the lowercase versions for the spacing modifiers, since that’s what people expect the defaults to be. I suppose you could go to the effort of making them case sensitive, but I don’t think people would ever use that feature much.

Hah, it took me nearly half a year to remember I'd started this thread, oops, sorry! Thank you for your answers. I'll duplicate the 00 range.
