"cities = cities.select(limit=1).execute().fetchall()" works well with this configuration, but leads to error in "nregion = places.select(places.c.name == iv2).execute()"
if "nregion = places.select(places.c.name == iv2).execute()" used first, then string conversion error appear at "cities = cities.select(limit=1).execute().fetchall()" Probably, MySQL charset setting is library-wide, but not connection- wide.
