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 in some way (esp. the prefix/suffix).

A gujarati (numeric) counter style is supported by the 3 main browser engines, so there appear to be no issues here. However, the only prefix/suffix supported by browsers is the full stop. Others should be allowed, where the user wants.

FIXED !

This gap is now fixed. For more details, see this GitHub issue, which is being used to track this gap. Please add any discussion there, and not to this issue.
