What are surrogates?

Surrogates, or surrogate pairs, are pairs of UTF-16 code values that encodes one special character such as an emoji.

Reference: https://unicode.org/faq/utf_bom.html#utf16-2

Chromium, Chrome and Edge

Chromium only supports BMP characters which includes 182 characters that can be treated as text or emojis depending on the surrogates.

As a result, Chromium-based browsers such as Chrome or Edge can only handle these surrogates.

There is no workaround to this limitation so if you need to run tests on Chrome and Chromium-based browsers, please only use BMP characters.

Firefox and Safari

Emojis and surrogate pairs are supported.
