title: Setting 'relaxedQueryChars' for embedded Tomcat
body: <p>How can I set <code>relaxedQueryChars</code> for Spring Boot embedded Tomcat?</p>
  
  <p>The connector attribute described <a href="https://tomcat.apache.org/tomcat-8.5-doc/config/http.html" rel="noreferrer">here</a>, but Spring Boot <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html" rel="noreferrer">documentation</a> has no such parameter listed.</p>
  
  <p>How to set Tomcat's Connector attributes in general?</p>
