with new installations, but older sites may want to turn it off
until they get their databases fixed up. See "UTF-8 database"
above for details.
schemacheck: when to let plugins check the database schema to add
tables or update them. Values can be 'runtime' (default)
or 'script'. 'runtime' can be costly (plugins check the
schema on every hit, adding potentially several db
queries, some quite long), but not everyone knows how to
run a script. If you can, set this to 'script' and run
scripts/checkschema.php whenever you install or upgrade a
plugin.
