Accented characters not displayed correctly

[AndroidLoop]

Describe the bug When grouping using the springdoc.group-configs[0].group and springdoc.group-configs[0].packages-to-scan properties, accented characters are translated to ó (see image below).

To Reproduce

• Spring version: Spring boot 2.6.3 (Extrated from POM) <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.6.3</version> <relativePath /> <!-- lookup parent from repository --> </parent>
• Version of springdoc-openapi: 1.6.4. POM: <dependency> <groupId>org.springdoc</groupId> <artifactId>springdoc-openapi-ui</artifactId> <version>1.6.4</version> </dependency>
• OpenAPI Description: JSON
• A sample code: Inside the application.properties, just must set a group with an accent in it. springdoc.group-configs[0].group=Nómina

Expected behavior

• The accent to be displayed correctly in the actual name of the definition as "Nómina"
