ICU MessageFormat — Nested select/plural (Polish)

Polish ICU MessageFormat catalog whose messages nest a select inside a plural branch and a plural inside a select branch, shipped with the argument bindings and the exact output each one must produce. Includes the '#' binding trap: inside a nested plural, '#' refers to the inner argument, so the outer count is written explicitly.

Testing contract

Expected to pass
Scenario
Feed each `cases` entry's arguments to an ICU MessageFormat implementation and format the named message.
Expected result
Every case produces its recorded string or plural category; a formatter that binds '#' to the outermost plural argument fails the `digest` message.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“ICU MessageFormat — Nested select/plural (Polish)” is a deterministic Novus Examples fixture for Internationalization, Localization catalogs, JSON parsing. Parallel text and accented, multi-script content — for testing translation pipelines, Unicode handling, and localization tooling.

Documented properties for this file: seed 20260807 · 2 messages · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Translation-catalog fixtures carry the same message set across formats, each with its native placeholder syntax. Test your i18n loader, catalog converter, or translation-memory tool, and use the RTL and CJK variants to check bidirectional text and Unicode handling.

Load the catalog with your i18n framework and verify placeholder interpolation and plural handling; the RTL and CJK variants exercise bidirectional text and font fallback.
