I've seen more and more people using different "Fonts" on Whi for their article titles, collection names, profile. Most people don't understand how that works and what are some of the unintended consequences of doing that.

I'm sure you can read "We Heart It" multiple times here:

𝒲𝑒 𝐻𝑒𝒶𝓇𝓉 𝐼𝓉 . 𝕎𝕖 ℍ𝕖𝕒𝕣𝕥 𝕀𝕥 . ᴡᴇ ʜᴇᴀʀᴛ ɪᴛ . Ⓦⓔ Ⓗⓔⓐⓡⓣ Ⓘⓣ . ฬє ђєคгՇ เՇ . ЩΣ ΉΣΛЯƬ IƬ . ωє нєαят ιт . 𝔚𝔢 ℌ𝔢𝔞𝔯𝔱 ℑ𝔱

But for a computer, none of these say "We Heart It". These are not "Fonts", they are special characters, like different letters. Like Chinese or Arabic characters, for a computer they're like a different alphabet.

So say you put a lot of effort into creating a collection about Puppies, you're hoping people will find it and follow your collection. If you call it "𝒫𝓊𝓅𝓅𝒾𝑒𝓈", people searching for "puppies" won't see your collection in the results. And the same goes to anything that uses these special characters.

Keep that in mind when you're posting or naming something. Adding a proper title / caption / description / tags to your content helps it be found in search.
