title: Do LATIN CAPITAL LETTER I (U+0049) and ROMAN NUMERAL ONE (U+2160) have unicode compatibility equivalence?
body: <p>Unicode defines two kinds of equivalence 000 canonical equivalence and compatibility equivalence. The example in Unicode Technical Annex #15 for compatibility equivalence is SUPERSCRIPT ONE (U+00B9) and DIGIT ONE (U+0031). It doesn't discuss characters that are visually indistinguishable.</p>
  
  <p>I am curious if characters that are visually indistinguishable have compatibility equivalence under the standard.</p>
  
  <p>Thanks..</p>
