 In the core code, this should be done for easier compatibility with html
 5. Polyglot markup only has 5 named entities. These need not be changed.
 They are amp, lt, gt, apos, and quot.

 Named entities are case-sensitive, which may cause problems. Numbers do
 not have case, which means they do not have this issue.

 Changing entities from named to numeric is a rather small task and it
 should greatly help overall portability. I am unaware of any
 implementation that supports only named entities.

 Also numeric entities should be infinitesimally quicker to look up by
 browsers, being a numeric index.

 Example
  * change › to ›
  * change ← to ←
 and so on
