Thank you, @moyogo ! I fully support this! And this is also candidate for a bug report at fontforge/fontforge.

So say, even if you acute and your combining acute are the same by design, you should use both in a differentiated fashion?

[moyogo]

@adrientetar /acute U+00B4 is a spacing character, /acutecomb U+0301 is a non-spacing character. /acute U+00B4 can be used to represent Latin-1 stuff like `quote-like´.
/acutecomb U+0301 can be used to represent decomposed acute letters like ɛ́.
There’s also another spacing acute, modifier letter acute U+02CA which can be used to represent the modifier letter acute (spaced like a letter, indicating tone) like eˊ.
They can have the same outline but they must not have the same advance width, only /acutecomb U+0301 should have zero advance width and OT-lookup anchors as a mark.
