Description
Customisable counters are needed for many languages.
There is no way for users to create local counter styles that are not built in to the browser, and users also often want to tweak the counter style for particular contexts (esp. the prefix/suffix).
Arabic script text uses local counter styles. While some of these are supported by some browsers, the set of symbols used and their order varies by language.
