Changelog:
===========
-This patch automatically disables the differing_executors health check for
methods which are also pytest parametrized tests, because those were mostly
false alarms (issue #3733).
-Building on recent releases, characters() now accepts _any_ codec=, not just
"utf-8" and "ascii".
-This includes standard codecs from the codecs module and their aliases,
platform specific and user-registered codecs if they are available, and
python-specific text encodings (but not text transforms or binary transforms).
-This patch by Reagan Lee makes st.text(...).filter(str.isidentifier) return
an efficient custom strategy (issue #3480).
