Hi,
Im currently working on a project where i want to give this thing a shot seen on the C/ and G/
Is there anyway to create a sort of outline around a diacritic so when it overlaps with a character it becomes visible? And if possible i would also love to avoid decomposing components.
This almost possible in Glyphs 3. You need to decompose the components but you can keep the original shape. Add a path that is a bit bigger as your mark, select it and click the “mask” checkbox in the lower right. Then add the path of the accent.
Are you trying to save as .ufo (Unified Font Object) or in Glyphs 2 format (see File > Font Info > Other)? Neither UFO nor Glyphs 2 support the new features, including masking. Make sure you switch the Font Info setting to Glyphs 3, and save as .glyphs.
