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 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 2.2 7.0.0 2.1 6.1.0 2.0 6.1.0 1.9 5.2.0
¹ Unicode 12.1 introduced a single character
Starting with Ruby 2.4, you can find out your Ruby version's Unicode support with:
RbConfig::CONFIG["UNICODE_VERSION"]
Ruby / Emoji
Ruby Version Emoji Version 2.7 12.1 2.6.2+ 12.0 2.6.1- 11.0 2.5 5.0
Starting with Ruby 2.6, you can find out your Ruby version's Emoji support with:
RbConfig::CONFIG["UNICODE_EMOJI_VERSION"]
