<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Superscripting can be down at a higher level (Rich Text, HTML ...) similar to bold face or italics. Latin-1 contains superscript a and o for Spanish order numbers, but for English order numbers with st, nd and th are superscripted at a higher level. In some cases you want to align ® with other circled letters, but for that purpose U+24C7 exists as a separate character distinct from U+00AE. There is no semantic difference whether ® is superscripted or not, so that would be a stylistic choice, which can be translated into markup like {\super ®} or<sup>®</sup>.</div>

The problem is that there is no bright line in typeface design of ® between “clearly small and superscripted” and “clearly large and not superscripted.” Variation selectors indicate a binary option: either the “normal” or traditional design, or else an alternative. Some fonts definitely show one style of ® or the other, of course, but there are many others that are somewhere in between — say, full-sized and slightly raised. Which binary option would encode that?<br/>
<br/>
It’s not the same as something like U+22DA LESS-THAN EQUAL TO OR GREATER-THAN, where the “equal” line in the middle either is clearly horizontal or else clearly follows the slant of the adjacent lines, with no middle ground.<br/>
