About this tool
These enclosed forms come from the Enclosed Alphanumerics block (U+2460 onward) and the Enclosed Alphanumeric Supplement (U+1F100 onward). Coverage is uneven by design: circled works for both letters and digits, parenthesized only has lowercase letters and digits 1–20 (no zero or capitals), and squared/negative-squared only cover capital letters, with no digit forms at all. Where a style has no glyph for a character, the original character is left in place and a note explains what was skipped.
