I want to input a special character just like ①, but I don't find how to. Can Mathematica make it?

  • $\begingroup$ Hi, take a look at Inset or Overlay. $\endgroup$ – Kuba Dec 7 '15 at 7:44

    $\begingroup$ The Unicode block Enclosed Alphanumerics \:2460 - \:24ff has a selection of such characters that will display circled numbers up to 20 in Mathematica running on OS X and maybe other operating systems as well. $\endgroup$ – m_goldberg Dec 7 '15 at 12:37
  • $\begingroup$ Thanks! It works on Windows.., and I found that we can modify the font format, size,color, and so on $\endgroup$ – WangFei Dec 8 '15 at 3:08
  • $\begingroup$ Thanks! but the last one FromCharacterCode[#] & /@ Range[9398, 9449] dosen't seem to work on my Mathematica. $\endgroup$ – WangFei Dec 8 '15 at 9:11

Follow the integer codes (to be used with FromCharacterCode) and hexadecimal codes (to be used with \:) for enclosed numbers. Although not asked, I added the codes for enclosed letters for completeness.

Enclosed numbers

FromCharacterCode[9450] (* \:24ea *)
FromCharacterCode /@ Range[9312, 9331] (* from \:2460 to \:2473 *)
FromCharacterCode /@ Range[12881, 12895] (* from \:3251 to \:325f *)
FromCharacterCode /@ Range[12977, 12991] (* from \:32b1 to \:32bf *)

enter image description here

FromCharacterCode /@ Range[9451, 9470] (* from \:24eb to \:24ff *)
FromCharacterCode /@ Range[10102, 10131] (* from \:2776 to \:2793 *)

enter image description here

Enclosed letters

FromCharacterCode /@ Range[9398, 9449] (* from to \:24b6 to \:24e9 *)

enter image description here


As mentioned by @m_goldberg in his comment, characters may not displayed on some operating systems, and as mentioned by @WangFeiBoy in his comment, the Style of the characters can be modified to some extent.


Generic code:

Graphics[{Circle[], Text[x^2 + y^2 < 1, {0, 0}]}]


generic example

Specific code:

Graphics[{Circle[], Text[1]}, ImageSize -> 24]


specific example


  • $\begingroup$ Thanks for your meaningful answer! but what I want to get is an "Enclosed Alphanumerics", just like what @m_goldberg said $\endgroup$ – WangFei Dec 8 '15 at 3:04
  • $\begingroup$ @WangFeiBoy, I do apologise for not providing the ideal solution. Could you please edit your question to include this requirement? What is the ideal output you are looking for? $\endgroup$ – e.doroskevic Dec 8 '15 at 9:35
  • $\begingroup$ Sorry I didn't express that clealy, but I think @Xavier have answered my doubts well. In fact your answer can solve my problem as well, in spite of some inconvenience. $\endgroup$ – WangFei Dec 9 '15 at 11:40
