Custom Font for Business Name in Local Results

Ive noticed some businessnes name appears in cool custom fonts like these ones , do anyone know how this can be replicated?

It's not exactly a custom font. They use Unicode encoding.
Search for example for "bold unicode characters" and you'll understand what I mean.

hint, hint : You can do it not only on the local and maps results, but in regular SERP's as well. Works wonders in some use cases.
