icu-plural-forms

Warning · An ICU plural does not have the forms of its language.

git8n check reports this rule as a warning. It fails only past --max-warnings.

Why it matters

An ICU plural picks a branch by the plural rules of the language. A form that the translation does not write shows the text of other, so a Polish « 5 elementów » becomes « 5 elementy ». A form that the language never uses is text that nobody reads.

What to do

Write a branch for each form of the language, and delete the others. Polish needs one, few, many and other; Japanese needs other only. An exact branch such as =0 is always allowed, and exact branches that hold all the numbers of a form replace it: =1 replaces one in English, but not in French, where one is 0 and 1. A form that only a number past 9999 takes, such as the many of French, is allowed and not needed.
