Support for UTF-8 POST/PUT/PATCH REST requests #733

Open donaldoakes opened 5 years ago

donaldoakes commented 5 years ago

The default character set per Java servlet spec is ISO-8859-1. MalformedInputExceptions can occur when non ISO-8859-1 characters are encountered in the request body (see below).

We should provide a way to configure the servlet to expect UTF-8 (and maybe this should be the default).
