openapi-generator-maven-plugin generate ascii with Description without escaping unsafe characters

Hi,
i am using the openapi-generator-maven-plugin to generate Ascii from a json file.
My Json File has some special Formatations like \n for new lines in the descirption, but the Plugin deletes the Formatation.

I found a Function in the openapi-generator and i think thats the reason why my Formatation is deleted.

  // remove \t, \n, \r
     // replace \ with \\
     // replace " with \"
     // outer unescape to retain the original multi-byte characters
     // finally escalate characters avoiding code injection
     return escapeUnsafeCharacters(
             StringEscapeUtils.unescapeJava(
                     StringEscapeUtils.escapeJava(input)
                             .replace("\\/", "/"))
                     .replaceAll("[\\t\\n\\r]", " ")
                     .replace("\\", "\\\\")
                     .replace("\"", "\\\""));

I am using the Plugin like this:

               <plugin>
                  <groupId>org.openapitools</groupId>
                  <artifactId>openapi-generator-maven-plugin</artifactId>
                  <version>5.3.1</version>
                  <executions>
                     <execution>
                        <goals>
                           <goal>generate</goal>
                        </goals>
                        <configuration>
                           <inputSpec>openapi.json</inputSpec>
                           <generatorName>asciidoc</generatorName>
                           <skipValidateSpec>true</skipValidateSpec>
                           <configOptions>
                              <useIntroduction>true</useIntroduction>
                              <useMethodAndPath>true</useMethodAndPath>
                              <useTableTitles>true</useTableTitles>
                           </configOptions>
                           <output>output</output>
                        </configuration>
                     </execution>
                  </executions>
               </plugin>

Is there a way to use the plugin with my Formatation?

Describe the solution you'd like

A Possibility to insert Formatations to the Descriptions

Start in modules/openapi-generator/src/main/java/org/openapitools/codegen/DefaultCodegen.java, focusing on the escaping function shown in the issue. Reproduce the behavior with the openapi-generator-maven-plugin 5.3.1 and an OpenAPI JSON description containing formatting characters, then verify that generated AsciiDoc preserves the requested formatting without unsafe-character injection.
