When to use it

&Acy; writes U+0410 (Cyrillic Capital Letter A), a capital letter from the Unicode Cyrillic block, encoded since Unicode 1.1. For Cyrillic text, type the letters directly on a UTF-8 page; named references for every letter make long text unreadable in source.

The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
