Command line used for generation

Command line:

java -jar ~/git/github/openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g spring -i tag.openapi.yaml -c java-config.json -o ./tags

And the configuration file

{
    "library": "spring-boot", 
    "groupId": "a.group.id", 
    "artifactId": "an-artifact-id",

    "apiPackage": "my.api.resource",
    "dateLibrary": "java8",
    "useBeanValidation": true, 
    "interfaceOnly": true, 
    "implicitHeaders": true, 
    "swaggerDocketConfig": true, 
    "useTags": true, 
    "allowUnicodeIdentifiers": false
}

Steps to reproduce

I tried allowUnicodeIdentifiers this weekend. I set it to true with the following openapi file.
It works as expected for interface. The parameter name use é character in the name.

default ResponseEntity<Void> sanitizeTagsGet(@ApiParam(value = "",required=true) @PathVariable("créance") String créance) {

When I set allowUnicodeIdentifiers to false, the result is the same. As I understand the parameter name should be sanitize.

default ResponseEntity<Void> sanitizeTagsGet(@ApiParam(value = "",required=true) @PathVariable("créance") String créance) {

For french language, it will be great to have the following result :

default ResponseEntity<Void> sanitizeTagsGet(@ApiParam(value = "",required=true) @PathVariable("créance") String creance) {

I'm not sure if the problem comes from sanitize methods or in mustache templates.
