Offset Curve filter limitation

[tyso]

I’m using the Offset Curve filter below to apply a stroke to brackets and diacritics etc. but not basic letterforms.

Instance filter:
GlyphsFilterOffsetCurve;16;16;1;0.5; include:acutecomb,bracketleft,bracketright

This works perfectly in the Glyphs preview:

But the exported font does not apply the stroke to the acute in the combined oacute glyph:

I realise this is an atypical setup but having this type of control would be a huge help.

Version: Glyphs 3.2 (3208)

Try adding it as a Prefilter.

Worked perfectly. Thank you Georg!
