Enclosed Alphanumerics

Enclosed Alphanumerics is a Unicode block of typographical symbols of an alphanumeric within a circle, a bracket or other not-closed enclosure, or ending in a full stop. The block is fully allocated. Within the Basic Multilingual Plane, a few additional enclosed numerals are in the Dingbats and the Enclosed CJK Letters and Months blocks. There is also a block with more of these characters in the Supplementary Multilingual Plane named Enclosed Alphanumeric Supplement (U+1F100–U+1F1FF), as of Unicode 6.0. The character U+20DD ◌⃝ COMBINING ENCLOSING CIRCLE from Combining Diacritical Marks for Symbols is available for composing other, arbitrary encircled symbols.
