Thanks, I missed this piece of info.
There’s this undocumented (I think) feature in TextMeshPro where it supports null-terminated strings. So if you do this:
tmpText.SetCharArray(new [] { 'h', 'i', (char) 0, 'y', 'o', 'u', });
It’ll show “hi”. Will that be the case with the API you’re talking about, or will you completely replace it with the char[], start, length API? It was usefull in some rare circumstances, but I can see it being clunky to support.
It seems to not have made it in 6.5 after all, docs show it’s in beta of 6.6.
