Question

What is the circular r at the end of word?

Answer 1

Enclosed R or circled Latin R (Ⓡ or ⓡ) is a typographical symbol. As one of many enclosed alphanumerics, the symbol is an "R" within a circle. Its most notable usage is as the registered trademark symbol (®), however, that has a different unicode because some fonts place the RTM symbol in superscript by default, but not enclosed R
