CombiNumerals Ltd lets you create any one or two-digit circled number, along with solid variants for the numbers 1-20 (solid variants are handled via OpenType features and/or glyph pallette selection, and only for 1-20). For non-solid circled numbers please use font character chart or glyph pallette to determine associated keystroke.
