What is an emoji sequence?

An emoji sequence is a series of Unicode code points that combine to display as a single emoji. For example, woman technologist is three code points: woman + ZWJ (U+200D) + laptop. The analyzer breaks these apart so you can see every component.

What types of sequences can the analyzer detect?

The analyzer identifies ZWJ sequences (joined with U+200D), skin tone modifications (Fitzpatrick modifiers U+1F3FB to U+1F3FF), keycap sequences (digit + VS16 + U+20E3), flag sequences (regional indicators), and tag sequences.

Why does a family emoji's .length return 8 in JavaScript?

JavaScript's .length counts UTF-16 code units, not visible characters or code points. Most emoji need 2 code units (surrogate pair), and ZWJ sequences contain multiple emoji plus joiner characters. Use Intl.Segmenter or a grapheme library for accurate counting.

What is the Zero Width Joiner (ZWJ)?

ZWJ (U+200D) is an invisible Unicode character that glues emoji together. When placed between two emoji, platforms that support the combination render them as a single glyph. If unsupported, the individual emoji display separately.

Can I analyze any text, or only single emojis?

You can paste any text. The analyzer will identify and break down all emoji sequences found in the input. Plain text characters are shown as regular Unicode code points.

What happens with unsupported sequences?

If a ZWJ sequence isn't supported by your platform, you'll see the individual component emojis displayed separately. The analyzer still shows the full sequence structure regardless of platform support.
