Description
Two regional indicator code points can encode a literal two-letter flag sequence.
Two regional indicator code points can encode a literal two-letter flag sequence.1
Decoding the pair reveals those letters without establishing that the code is assigned or currently used.
When to use Flag Emoji to ISO Alpha-2 Decoder
Use this tool to apply the stated flag emoji to iso alpha-2 decoder operation with an explicit input and unit basis.
How to use Flag Emoji to ISO Alpha-2 Decoder and how it works
- Establish the measurement basis and units described above.
- Enter actualRegionalIndicatorPair and run the tool.
- Read result.literalAlpha2Code using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualRegionalIndicatorPair | Regional indicator pair, on the basis specified in the algorithm. | string | required; further conditions in the algorithm |
Require exactly two code points from U+1F1E6 through U+1F1FF. Convert their offsets to uppercase ASCII letters and concatenate.
letter = A + (indicator − U+1F1E6) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.literalAlpha2Code | Decoded uppercase two-letter string; code assignment is not checked. | string |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
