Emoji are Unicode characters and sequences. Rendering can differ by operating system, font, app, and Unicode/Emoji version. Sequence handling here follows Unicode Emoji structure; the searchable catalog is curated rather than an exhaustive emoji encyclopedia.

Decode regional-indicator flag emoji into two-letter country codes or generate flags from alpha-2 codes. The table keeps invalid tokens visible instead of silently dropping them.

Not every flag decodes to two letters

Two regional-indicator symbols can be converted back to a two-letter code. Other flag-like emoji, including some subdivision or special flags, are multi-code-point tag sequences and do not have the same simple country-code mapping.

Flag decoding requires an RGI regional-indicator sequence

A two-indicator pair must be a recognized RGI flag sequence before it is converted back to a region code.
