Alpine linux gb18030 support

I'm working on a Java/Tomcat/Spring project, and setup a docker as my dev environment. The app works fine in our dev server because it's using UTF-8 as system charset. But our customer's production environment is setting up using GB18030, and all operation involving file in chinese are failed, including upload file with chinese file name, reading file with chinese content, etc.

I'm understand I need to do a translate between UTF-8 and GB18030 before and after those operation, but first of all, the dev server should simulate the customer's production environment.

So, my question is, does Alpine linux support i18n, or specifically GB18030? If so, how can I set these up? Thanks.
