  17  * Common UTF-8 sequences.
  18  * Although we've supported UTF-8 encoded source files since April 2019 /
  19  * bd75f5af0a, it can be useful to explictly encode some code points in
  20  * order to ensure that we use them consistently.
  21  *
  22  * Sequences can be found at
  23  * http://www.fileformat.info/info/unicode/
  24  * http://www.utf8-chartable.de/
  25  * and other places
  26  *
  27  * Please be conservative when adding code points below. While many modern
  28  * systems default to UTF-8 and handle it well, some do not. The Windows
  29  * console is a notable example. As a general rule you probably shouldn't
  30  * stray too far from code page 437 or WGL4:
  31  * https://en.wikipedia.org/wiki/Code_page_437
  32  * https://en.wikipedia.org/wiki/Windows_Glyph_List_4
