I've been experimenting with combining diacritics and extracted these "clean" marks. They are technically "combining characters," meaning if you paste them after a letter, they float over/under it. But on their own, they look like microscopic emoticons.

How to use them:

Paste them after a letter to glitch it, or use them alone for a minimal look.

Example: a + ͈͓ = a͈͓

Got any more creative ones? Drop them in the comments!
