ICU MessageFormat: Apostrophe and brace quoting

The quoting rules that make ICU messages surprising: a single quote starts a literal section only when the next character is one ICU cares about, a doubled '' is always one apostrophe, and '#' inside a plural branch is a literal hash. Every message is paired with the exact string it must produce.

ICU MessageFormat: Nested select/plural (Arabic)

Arabic 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.

ICU MessageFormat: Plural offset (English)

The 'Rana and 5 others like this' pattern: ICU plural arguments with offset:1 and offset:2, where the explicit =0/=1/=2 selectors match the RAW value but '#' prints the value MINUS the offset. Ships every boundary case with its expected output.

ICU Plural-Category Probe: Welsh (six categories, both kinds)

Welsh is the only CLDR locale that uses all six plural categories for cardinals AND all six for ordinals, which makes it the strongest single probe for a plural-rule engine. Each branch names its own category so the assertion is about selection, not wording, and the two rule sets disagree for n = 4, 5, 7, 8 and 9.

ICU selectordinal: English ordinal suffixes

English st/nd/rd/th suffixes done properly, via ICU selectordinal rather than a hand-written switch. The case list covers the teens (11th, 12th, 13th) and the wrap-around (21st, 102nd, 111th) that a naive n % 10 lookup gets wrong.

Idealised Rock-Salt Structure: Crystallographic CIF (.cif)

A single-data-block CIF describing an idealised rock-salt lattice: cell parameters, space group, a symmetry-operation loop and an atom-site loop with fractional coordinates and occupancies. The '?' in the temperature field is CIF's marker for unknown, which is not the same as an empty value.
