There is a system wide setting that changes all non-Unicode text encoding to another code page e.g CP932 for Shift-JIS. Third party tools are available to do the same conversion on a per application basis.

It’s not as bad as trying to load some really old CJK web pages on mobile devices: few mobile browser has an accessible option to select character encoding and there appears to be none on iOS. The only option is to change the system language and that didn’t always work for more obscure character codes.
