English to Spanish translation not working in JSP file

Question

I am using this code to read property

    <div class="form-group">
                            <label for="training" class="form-check-label mt-30">                           
                               <form:checkbox id="training" path="isTraining" class="form-check-input"/><em><spring:message code="sol.settings.training.label"/></em>
                            </label>
                            <input type="button" class="bbtn bbtn-secondary pull-right mt-30" onclick="window.location='/sol/list/page/redirectToSolutionView.htm?filterId=MYITS&showAlert=false&searchText='" 
                            title="Cancel Solution"                     
                             value="<spring:message code='create.sol.page.cancelsol'/>"
                            
                            
                            />
                        </div>

The english translation works fine but for Spanish the data is not coming fine , it should come as create.sol.page.cancelsol = Cancelar solución but here instead of solución it comes as "Cancelar soluci�n". Why there is a question mark here?

Answer 1

This is probably a response configuration issue. The page is providing a response with content encoding different than UTF-8 (say, ISO-8859-1). This will make the symbols for accented characters such as "ñ", "ç" to appear as possibly unavailable symbols in the ISO-8859-1 encoding, making it to appear as the question mark.

I believe this article SpringBoot response charset errors will be of help to you: it explains how to configure springboot servlets to force a specific charset encoding for responses.
