In all these reports, part of the analysis is also to determine
how those specifications deviate (or not) from PEP 3131.

In this case, it seems that:
- JS additionally allows $
- PEP 3131 additionally considers the stability extensions
  (Other_ID_{Start|Continue}). That may be because the JS
  specification was based on an earlier version of UAX#31,
  which perhaps didn't had the need for this stability
  feature.
- JS uses Unicode 3.0, whereas Python uses whatever Unicode
  version lives in unicodedata.
