The Ruby core team cares a lot about Unicode, and this is why we have pretty good Unicode support in the language.
Even though the Unicode standard evolves constantly - it gets updated at least once a year - Ruby's Unicode support is often only a little bit behind the current version of Unicode. The following tables list which Ruby version supports which version of Unicode / Emoji:
Ruby / Unicode
| Ruby Version | Unicode Version |
|---|---|
| 3.3 | 15.0.0 |
| 3.2 | 15.0.0 |
| 3.1 | 13.0.0 |
| 3.0 | 12.1.0 |
| 2.7 | 12.1.0 |
| 2.6.3+ | 12.1.0¹ |
| 2.6.2 | 12.0.0 |
| 2.6.1- | 11.0.0 |
| 2.5 | 10.0.0 |
| 2.4 | 9.0.0 |
| 2.3 | 8.0.0 |
