User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

  1. Navigate to https://en.wikipedia.org/w/index.php?title=Celsius&oldid=922584477#Unicode_character
  2. Press Ctrl + F to search for text within the page
  3. Search for either "°C" (U+00B0 ° DEGREE SIGN + U+0043 C LATIN CAPITAL LETTER C) or "℃" (U+2103 ℃ DEGREE CELSIUS)

Actual results:

The search strings "°C" and "℃" are not treated as identical; searching for one does not find instances of the other.

Expected results:

According to the Unicode standard, those two strings should be treated as identical for search purposes. This is specified in the subsection titled "Unit Symbols" in section 22.2 of the Unicode 9.0.0 standard, found here: https://www.unicode.org/versions/Unicode9.0.0/ch22.pdf
